On my setup (Dell 6420 with integrated HD3000; shows as 8086:0126 (rev 09) in lspci; running Debian 2.6.38-2), the bug appears only after a while (so it's hard to reproduce).

I tried your new kernel anyway. I got the error just once, after the boot:
[ 73.270170] [drm:i915_hangcheck_ring_idle] *ERROR* Hangcheck timer elapsed... blt ring idle [waiting on 11744, at 11744], missed IRQ?
I will stick with this kernel until the bug happens again (or not ;-))
Just tried neverball for a couple of minutes, it didn't trigger the bug.

Note: I don't know if it's relevant, but since I installed this kernel, opening the lid of the laptop will turn the screen to black. The screen remains OK when I close the lid, but when I re-open it, it goes black. It's not off (I still see the backlight), just black. It is then stuck in that state: switching back to textmode won't help. However, if I suspend to RAM and resume, the screen will work again. Before using this kernel, this bug occured exactly 50% of the time (i.e., I could close+open once, and the 2nd time would trigger the bug).
