I guess you are using this huge virtual display to drive multiple displays with xrandr. I have the same chipset (GM965) and encountered the same bug (though it was the back buffer that failed to allocate). It helped to reduce the virtual desktop size.

Could you try to disable this big virtual display in xorg.conf and report back? I do recognize that those big virtual sizes work in previous non-GEM kernels.

when starting X,X will crash and we get below error:
(EE) intel(0): [drm] failure adding irq handler
-------------------------------------
we try to bisect and find this commit(from eric's kernel tree) which cause the issue:
commit 7297294597b9be5bb377d996a5bcbcda64417add
Author: Kristian Høgsberg <krh@redhat.com>
Date:   Wed Aug 20 11:04:27 2008 -0400

    i915 gem: install and uninstall irq handler in entervt and leavevt ioctls.

 It also happens on G33 and 945g
Comment 6 Tobias Hain 2008-09-08 00:54:13 UTC 
Most likely a duplicate of
https://bugs.freedesktop.org/show_bug.cgi?id=17446

Try the suggested commit 1063ef90845d7c84f4799ac34bd23ef37860bdc0 of eric's kernel there.

it works well with commit 1063ef90845d7c84f4799ac34bd23ef37860bdc0.

Please close the old bug and open a new one instead of changing the topic of a bug several comments in.

The new topic of this bug is a dupe of 17446.

Haien, remember to file a new bug for the original issue (huge virtual display). Please also test if it's reproducible with non-GEM kernel.

and it can not reproduce with non-GEM kernel ,there is another issue with non-GEM kernel ,see bug 17621.
