S3 power drain on Thinkpad R32 (fixed?)

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.

Yes, but will it wash my dishes?

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