So with low settings you will have less power consumption because gpu will be down-clocked. dypm is not the best solution in term of power consumption, because it changes only mem frequencies, the gpu one is the same as on high power profile.

I also looked at the list of opened bug reports, but I haven't tried yet to open a new one or ask on IRC.

It's got a 6 cell battery. Why not Debian? Squeeze comes up with 800 x 600 display resolution which sucks on a native 1280 x 720 display. Wheezy barfs during the install at the detect hard disks and partitions for some reason. I'm just a timid tinderer so don't have the skills and confidence to poke further.

And have you tried asking on #radeon on freenode or https://bugs.freedesktop.org/enter_bug.cgi?product=DRI&component=DRM/Radeon for advice?
