DPMS broken on xf86-video-intel-1.9.94

[JM Ibanez]

Hi!

Currently, DPMS seems to be broken for me. I have yet to pinpoint
whether it's on DPMS suspend/off or on DPMS on.

I'm currently on Ubuntu Feisty, running on Xserver and the intel driver
both compiled from git. What I'm seeing is the system locks up hard when
the screen is blanked. gnome-power-manager is set to turn off the screen
after 40 minutes; the display also goes to sleep when I close the lid.

I've (sort of) worked around this by setting gnome-power-manager not to
turn off the display (both lid and by timer).

I'll see if I can tease more info; but basically, that's the problem.

(By "locks up hard" I mean that hitting any key on the keyboard elicits
no response from the system, the kernel's magic SysRq combos don't work,
and the only way to get back to work is to hold the power button.)
