Yes, you're right, removing DRI module from my xorg.conf dropped a bit
the power consumption, and the processor reached the C3 and C4 states !
The difficulty here was that the top wake-up task was interrupts from
hardware, and as a lot of them shared the same interrupt (USB,
pcmcia, )...

Yes, it's the default Gnome desktop... but I think the number of
wake-ups by all Gnome (or other) apps is due to the fact I don't have
HPET activated, so the processor can't sleep a long time...
