Thanks for the response. Does it matter that its 2.6.18-rc4 and not 2.6.18-rc3? I compiled rc3 a while ago and just tried it out and didn't get a significant improvment. Specifically, suspending to ram using powersave still takes about 30 seconds to resume and suspending to disk doesn't seem to work at all (which I'll try to debug). I even used the new version of suspend downloaded from sourceforge (which doesn't go through powersave) and it still takes ~30 seconds to come back to life. Should I be expecting 2-4 seconds resume time from ram (someone else on this list told me they could get that)?
I also notice that when I suspend to ram if I stare at the screen from different angles I can still see some faint characters in the background which makes me think that at some level the screen is not completley off. I see this with the open source radeon driver (I'm not sure if it also happens with the proprietary ATI driver).
Does the s2ram with the new kernel work fast (e.g. < 10 seconds) and effectively (use very little battery) for everyone or are others have similar problems?
Thanks,
Sheer

Eh, just don't use proprietary drivers.

Find out which parts produce the heat... then fix those drivers.

Try with 2.6.18-rc4-vanilla.

Specific to your machine -- but we are eating too much power on many
machines. See radeon problems on thinkpads.

That's probable cause.

You need new kernel, not new s2disk.
