S3 power drain on Thinkpad R32 (fixed?)

S3 power drain on Thinkpad R32 (fixed?)

[Brian Perkins]

So I had essentially been told that the improving the power drain due to 
the video subsystem during suspend to RAM was a hopeless case (it's a 
Radeon mobility M6 system).

However, I noticed some interesting comments in the radeonfb module and 
tried installing it and noticed that it improved battery life 
dramatically and doesn't need any video_post nonsense. It even seems to 
play OK with X, which is great.

I spoke to BenH who said that there may be recent ACPI fixes that 
address this issue outside of radeonfb.  Does anyone know about this? 
That would be nice, since I don't quite trust radeon and radeonfb to be 
reliable together.

The kernel version is apatched 2.6.12-1.1387_FC4 with some minor tweaks 
and a patch that's supposed to make radeon and radeonfb work better 
together.

I just wrote a thinkwiki article that explains the solutions, including
the official FC4 kernel:
