Proposal for resolving powernowd/apmd vs. (k)powersave conflict

I have reinstalled my notebook (Flight4 + all updates) - this time
without ubuntu-desktop. Latest Dapper kernel has broken hibernation
(suspend to disk), but it works with 2.6.15-15. See bug

No, I did not have X PM disabled.
Now on clean system, I got the same error as Achim. Reboot helped.
It may be just timing issue and at first install acpid was restarted
faster than X was able to take it over...

I have tried all kind of possibilities and did not help. Only new hint
was vga=normal, but even this one does not help me. :-( I just think
that ATI FireGL V5000 is too strange for kernel to wake it up
Suspend to Disk works now (with 2.6.15-15 kernel).

I am now following you on this - which package is supposed to install
/lib/ libsysfs-dev?  What is binNMU???
