i read the bios mod link... i am, also, not sure about the info that could be change on the bios. i am not an expert, but is not the same to change the dsdt ??? sorry for my ignorance...
now i am looking into DSDT , to understand the WMI and some PEGP info ... i wish i could have lots of vaio DSDT to compare that sorts of things...
perhaps re-writing the nvidia drivr from FreeBSD driver could help...
i don't know... i am thinking on selling this SHI* out...
thanks for your effort!
If you want I can include my DSDT from a Sony Vaio FZ21M with the "old" 8400M GT only, but I'm on Windows 7 32bit.
It's the same thing for you the DSDT-Windows side?
if you include your DSDT i will glad....
i remember alinux forum that i have posted the links a time ago maybe in tthat tread with many dsdt collected from vaio but i don't retrieve this from google but maybe if your lucky with "vaio dsdt linux "as keyward you should find or in following my old posts
so i perform alittle quest and find something useful for modding dsdt here are the news i've found :
<h2 class="date-header">Tuesday, 7 September 2010</h2> </a> <h3 class="post-title entry-title"> Sony Vaio VPCZ12 DSDT hybrid graphics info </h3> The Sony Vaio VPCZ12 model comes with a ACPI DSDT table that has two methods to allow for switching on/off the discrete graphics card:
If (LEqual (_T_0, 0x03))
Store (0xA003, P80H)
If (LEqual (And (Arg3, 0x03), Zero))
Return (^^P0P2.DGPU._STA ())
If (LEqual (And (Arg3, 0x03), One))
If (LEqual (And (Arg3, 0x03), 0x02))

my model dsdt:
Would be nice to see the DGPU section too. I guess it's no nVidia device or some meta device. We have no on/off method in our dsdt.

Satellite M645 (PSMPMU-S4047) \_SB.PCI0.P0P2.VGA._OFF \_SB.PCI0.P0P2.VGA._ON VGA compatible controller : Intel Corporation Core Processor Integrated Graphics Controller [8086:0116] 00:02.0 VGA compatible controller : nVidia Corporation GT216 [GeForce GT 330M] [10de:0a2b] 01:00.0 Works great with kernel 2.6.38-8-generic. Earlier kernel versions worked, but froze as soon as any key-presses were made. No nVidia proprietary drivers are used. Using acpi_call, I was able to achieve a battery mA with discrete disabled: ~1000-1300mA. with discrete enabled: 1900-2500mA

EDIT: I found this table: GT330M VGA acpi device, the last table, see the very last table: If we get the the dsdt from Toshiba Satellite M645, maybe the VGA dsdt device could help us? Do you have a VGA device in your DSDTs?
Man, there is no ON / OFF functionality in your dsdt... Why do you wasting our time?
