iBook G3 sleep/FC-3 PPC
Quick note before I forget. FC-3 PPC pretty much just works, really, everything in it is so cool and sleep works, among other good things. udev problems are fixed, and G3 sleep even with X running and stuff works – the FC-2 tree was plagued with a broken GNOME control-center, the FC-3 tree is plagued with a haldemon.
/etc/init.d/haldemon stop before putting the iBook G3 to sleep is all you need. Of course if you have a G4 with the recent sleep patch and dwmw2’s kernels, I have no idea how it works, though I’m assured it does.
