I can't turn off my ATI adapter. I have applied the fix, but still lspci | grep VGA
gives
00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
01:00.0 VGA compatible controller: ATI Technologies Inc M92 LP [Mobility Radeon HD 4300 Series] (rev ff)
and my power consumption is about 15W (Wi-Fi on).
I run ubuntu 9.10, kernel 2.6.31-14-generic. BIOS version 2.30
