Yeah, me too…
And blackosx, you are not alone… I was working really hard in a last 24h to crack this one… What most is troubling me is the fact that I was managed to restart my computer properly a couple of times, but now it simply refuses to work… I’m really confused what happens, because as I said, I had 3 or 4 times CMOS reset and then I was made some changes in DSDT and managed to make 3 times sleep/wake/restart operation properly. After second rollback it didn’t want to work again… I regret now one thing and that is the fact that I didn’t backup my DSDT from that stage, but I was continue to mass with him further… During my work I was really made a lot of drastic changes in it and now I’m not sure anymore how some parts was looked like in that very moment. I was even manage to built another variation of my DSDT which is also working vanilla but this one is built from original code components for Device (RTC), (HPET) and (TIMR), which I was cut and paste directly from MacPro3,1 DSL. So here is my observation for that part…
This is a piece of code that I was using previously:
Device (HPET)
{
Name (_HID, EisaId ("PNP0103"))
Name (ATT3, ResourceTemplate ()
{
IRQNoFlags ()
{0}
IRQNoFlags ()
{8}
Memory32Fixed (ReadWrite,
0xFED00000, // Address Base
0x00000400, // Address Length
)
})
Name (ATT4, ResourceTemplate ()
{
})
Method (_STA, 0, NotSerialized)
{
Return (0x0F)
}
Method (_CRS, 0, NotSerialized)
{
Return (ATT3)
}
}
Device (TMR)
{
Name (_HID, EisaId ("PNP0100"))
Name (ATT6, ResourceTemplate ()
{
IO (Decode16,
0x0040, // Range Minimum
0x0040, // Range Maximum
0x00, // Alignment
0x02, // Length
)
})
Method (_CRS, 0, NotSerialized)
{
Return (ATT6)
}
}
Device (RTC)
{
Name (_HID, EisaId ("PNP0B00"))
Name (ATT0, ResourceTemplate ()
{
IO (Decode16,
0x0070, // Range Minimum
0x0070, // Range Maximum
0x00, // Alignment
0x02, // Length
)
})
Name (ATT1, ResourceTemplate ()
{
IO (Decode16,
0x0070, // Range Minimum
0x0070, // Range Maximum
0x00, // Alignment
0x02, // Length
)
})
Method (_CRS, 0, NotSerialized)
{
Return (ATT0)
}
}
This is the MacPro3,1 code:
Device (HPET)
{
Name (_HID, EisaId ("PNP0103"))
Name (BUF0, ResourceTemplate ()
{
IRQNoFlags ()
{0}
IRQNoFlags ()
{8}
Memory32Fixed (ReadOnly,
0xFED00000, // Address Base
0x00000400, // Address Length
_Y09)
})
Method (_STA, 0, NotSerialized)
{
If (LGreaterEqual (OSYS, 0x07D1))
{
If (HPAE)
{
Return (0x0F)
}
}
Else
{
If (HPAE)
{
Return (0x0B)
}
}
Return (0x00)
}
Method (_CRS, 0, Serialized)
{
If (HPAE)
{
CreateDWordField (BUF0, \_SB.PCI0.LPCB.HPET._Y09._BAS, HPT0)
If (LEqual (HPAS, 0x01))
{
Store (0xFED01000, HPT0)
}
If (LEqual (HPAS, 0x02))
{
Store (0xFED02000, HPT0)
}
If (LEqual (HPAS, 0x03))
{
Store (0xFED03000, HPT0)
}
}
Return (BUF0)
}
}
Device (RTC)
{
Name (_HID, EisaId ("PNP0B00"))
Name (BUF0, ResourceTemplate ()
{
IO (Decode16,
0x0070, // Range Minimum
0x0070, // Range Maximum
0x01, // Alignment
0x08, // Length
)
})
Name (BUF1, ResourceTemplate ()
{
IO (Decode16,
0x0070, // Range Minimum
0x0070, // Range Maximum
0x01, // Alignment
0x08, // Length
)
IRQNoFlags ()
{8}
})
Method (_CRS, 0, Serialized)
{
If (HPAE)
{
Return (BUF0)
}
Return (BUF1)
}
}
Device (TIMR)
{
Name (_HID, EisaId ("PNP0100"))
Name (BUF0, ResourceTemplate ()
{
IO (Decode16,
0x0040, // Range Minimum
0x0040, // Range Maximum
0x01, // Alignment
0x04, // Length
)
IO (Decode16,
0x0050, // Range Minimum
0x0050, // Range Maximum
0x10, // Alignment
0x04, // Length
)
})
Name (BUF1, ResourceTemplate ()
{
IO (Decode16,
0x0040, // Range Minimum
0x0040, // Range Maximum
0x01, // Alignment
0x04, // Length
)
IO (Decode16,
0x0050, // Range Minimum
0x0050, // Range Maximum
0x10, // Alignment
0x04, // Length
)
IRQNoFlags ()
{0}
})
Method (_CRS, 0, Serialized)
{
If (HPAE)
{
Return (BUF0)
}
Return (BUF1)
}
}
So I was change my code with this one (MacPro3,1 routinne)...
Device (HPET)
{
Name (_HID, EisaId ("PNP0103"))
Name (BUF0, ResourceTemplate ()
{
IRQNoFlags ()
{0}
IRQNoFlags ()
{8}
Memory32Fixed (ReadOnly,
0xFED00000, // Address Base
0x00000400, // Address Length
_Y0D)
})
Method (_STA, 0, NotSerialized)
{
If (LEqual (OSFL (), Zero))
{
If (HPTE)
{
Return (0x0F)
}
}
Else
{
If (HPTE)
{
Return (0x0B)
}
}
Return (Zero)
}
Method (_CRS, 0, NotSerialized)
{
If (HPTE)
{
CreateDWordField (BUF0, \_SB.PCI0.SBRG.HPET._Y0D._BAS, HPT)
If (LEqual (HPTS, One))
{
Store (0xFED00000, HPT)
}
}
Return (BUF0)
}
}
Device (TIMR)
{
Name (_HID, EisaId ("PNP0100"))
Name (BUF0, ResourceTemplate ()
{
IO (Decode16,
0x0040, // Range Minimum
0x0040, // Range Maximum
0x00, // Alignment
0x04, // Length
)
})
Name (BUF1, ResourceTemplate ()
{
IO (Decode16,
0x0040, // Range Minimum
0x0040, // Range Maximum
0x00, // Alignment
0x04, // Length
)
IRQNoFlags ()
{0}
})
Method (_CRS, 0, Serialized)
{
If (HPTE)
{
Return (BUF0)
}
Return (BUF1)
}
}
Device (RTC)
{
Name (_HID, EisaId ("PNP0B00"))
Name (BUF0, ResourceTemplate ()
{
IO (Decode16,
0x0070, // Range Minimum
0x0070, // Range Maximum
0x00, // Alignment
0x02, // Length
)
})
Name (BUF1, ResourceTemplate ()
{
IO (Decode16,
0x0070, // Range Minimum
0x0070, // Range Maximum
0x00, // Alignment
0x04, // Length
)
IRQNoFlags ()
{8}
})
Method (_CRS, 0, Serialized)
{
If (HPTE)
{
Return (BUF0)
}
Return (BUF1)
}
}
This working 100% in SL, however didn't fix CMOS reset in Lion...
Eventually I was decide to rollback everything on my original BIOS code and this is what I'm using now...
Device (HPET)
{
Name (_HID, EisaId ("PNP0103"))
Name (CRS, ResourceTemplate ()
{
IRQNoFlags ()
{0}
IRQNoFlags ()
{8}
Memory32Fixed (ReadOnly,
0xFED00000, // Address Base
0x00000400, // Address Length
_Y0D)
})
OperationRegion (^LPCR, SystemMemory, 0xFED1F404, 0x04)
Field (LPCR, AnyAcc, NoLock, Preserve)
{
HPTS, 2,
, 5,
HPTE, 1,
Offset (0x04)
}
Method (_STA, 0, NotSerialized)
{
If (LEqual (OSFL (), Zero))
{
If (HPTE)
{
Return (0x0F)
}
}
Else
{
If (HPTE)
{
Return (0x0B)
}
}
Return (Zero)
}
Method (_CRS, 0, NotSerialized)
{
CreateDWordField (CRS, \_SB.PCI0.SBRG.HPET._Y0D._BAS, HPT)
Multiply (HPTS, 0x1000, Local0)
Add (Local0, 0xFED00000, HPT)
Return (CRS)
}
}
Device (TIMR)
{
Name (_HID, EisaId ("PNP0100"))
Name (_CRS, ResourceTemplate ()
{
IO (Decode16,
0x0040, // Range Minimum
0x0040, // Range Maximum
0x00, // Alignment
0x04, // Length
)
})
}
Device (RTC)
{
Name (_HID, EisaId ("PNP0B00"))
Name (_CRS, ResourceTemplate ()
{
IO (Decode16,
0x0070, // Range Minimum
0x0070, // Range Maximum
0x00, // Alignment
0x02, // Length
)
IRQNoFlags ()
{8}
})
}
During this code exchange I notice two things...
When I rollback:
IRQNoFlags ()
{0}
for Device (TIMR), my sound is messed up, and...
IRQNoFlags ()
{2}
for Device (PIC), breaks sleep operation...
None of these changes was manage to fix CMOS reset in Lion!!!

and don't think so much to it... 
). Hopefully you can re-trace your steps and reproduce it because I haven't a clue as to what you would have done to fix it.
