[Intel-gfx] graphics lock up on logout/shutdown

I just got a shiny new laptop with an Intel gm45 based gpu.

When I select log out or shutdown from within kde4 (compositing enabled or 
not) X will go away, and the screen will show what ever was on the terminal 
JUST before X started up. In most cases that's the text cursor at the top left 
of the screen. That's with modesetting enabled. With modesetting disabled, X 
will go away and the text consoles are seriously messed up, text is weirdly 
scrolling at the top of the screen, and the whole thing seems to be flashing.

I'm running Debian Sid on the laptop, and have tried both the intel driver in 
sid, and the one in experimental. No matter what the outcome is the same.

That said, the machine isn't fully locked up, just the graphics are.

here's what the xorg log says:

Backtrace:

12: /usr/bin/X [0x4326a9]

Fatal server error:
Caught signal 11.  Server aborting

And its the same every time (for the most part). And its the same with KMS or 
no KMS, same with or without compositing enabled in KDE4, and its the same 
with either version of the intel driver in Sid (2.7.1) or Experimental 
(2.7.99.1)


I'm wondering if there's a fix for this in git or something I might do to be 
able to logout without having to reset the machine from ssh or the power 
button.
