Thanks a lot for looking at this. I have updated to kernel 2.6.25 (I was still
using 2.6.22 to avoid iwlwifi...), and stated using kpowersave, and so far it
is good.
Question after reading your mail is: what kernel version will be in Lenny?
2.6.24 or 2.4.25?

PS: Michael, i have cc'ed you in case you have something interesting to say
wrt kpowerposave.
