I'll try it but... I couldn't do the suspend to ram when I run it into X
or when the Xorg was ran, then iBook doesn't wake up and I get a black

Sleep only worls when I'm in a terminal and I don't ran X before calling
iBook go to sleep.

I'm running kernel 2.6.11-r4 in a gentoo with Xorg.

Sorry for the OT and... thanks!
