Sleep freezes computer--Didn't work in the first place (iAtkos 10.5.7 to 10.5.8 upgraded)

[NinjaTails]

When I had the 10.5.7 ver. with the Voodoo kernel (still do, actually) sleep only turned off the hard drives, not the graphics.

 

Now sleep causes the computer to just hang and it won't "wake up", even though it never actually gets to sleep mode.

 

I'm running on a 2.4 Ghz Pentium 4 processor, ATi Radeon 9600 graphics (that are choppy), and using a Logitech Speakerphone as my sound source (which is a vanilla kext so I don't have to worry about it).

 

I'd like sleep to work but the computer is being used as my server so it isn't all that important, I was just wondering if there was a way to prevent it from hanging when it tries to sleep besides disabling sleep everywhere--it's useful every once in a while.

 

It should be noteworthy that installing AppleIntelCPUPM.kext neither hindered nor helped this problem.
