[SOLVED?] Higher power consumption after resuming on 945GM

Some minutes after my netbook resumes from hibernation (happens with tuxonice and s2disk), i clearly see it starts to consume more power than when it boots 'normally'.

powertop shows that Kworker is waking up the cpu about 300 times per second.
powertop-1.99 (git version from aur) shows that it is repeatedly executing flush_to_ldisc()

So i started to kill all the processes one by one to find the culprit, and it seems that is Xorg to cause the problem (even a blank screen without clients causes the wakeups)

This happens on an intel chipset, it is 945GM (Asus eeepc 1005HA).
On another box with nvidia ion hardware and about same packages, this don't happen, so i think that probably something is wrong with intel video driver.

Using arm, i rolled back xf86-video-intel driver from 2.13 to 2.10 and then to 2.12 with the needed dependancies, here's the log:

I'm still crossing my fingers, but it seems that the issue is gone, as it is running from hibernation for more than 4 hours without issues.
I even opened a bug report upstream here:
https://bugs.freedesktop.org/show_bug.cgi?id=32647

- Does anyone noticed this on similar hardware?

- Why the latest upgrade installed a git package? (intel-dri-7.9.0.git20101207-2)

Ok, upgraded intel driver and left xorg-server to 1.9.0 (as long as it's dependancies).
It is still working fine, it appears to be an xorg issue to me, but it has to be related to other things anyway, because on other hardware it wont happens, who knows...
