Good day,
Guido Guenther maintains some patches against 2.6 that I found very
usefull :
software suspend :

| Works here without problems for several days now, patch is at
| http://honk.physik.uni-konstanz.de/~agx/linux-ppc/kernel/2.6.11-rc4-agx0.diff
| Cheers,
| -- Guido
Again From debian-ppc on 04 december 2004 :
| The patch contains some other small goodies such as a selectable HZ
| value (default is 1000, 100 saves some battery) and some alsa and
| cpufreq fixes.
| Please note that this patch still conflicts with suspend to ram, so you
| won't be able to use both.
| Cheers,
| -- Guido
patch is at :
http://honk.physik.uni-konstanz.de/~agx/linux-ppc/kernel/
and attached to this bug report.
