Bug#432110: i915: x server lockups

["Radek \"Mrkva\" Pilar" <RPilar@seznam.cz>]

This bug occurs even in unstable (xserver-xorg-video-intel version 2:2.2.1-1).
Mine graphics card is Intel GM965. The only change is, that screen doesn't 
turn black with cursor, but simple freezes. This happens mostly (but not 
only) when using 2D graphics acceleration (playing xmoto for example).
Here is my output from kdm.log, hope it helps:

The XKEYBOARD keymap compiler (xkbcomp) reports:
> Warning:          Type "ONE_LEVEL" has 1 levels, but <RALT> has 2 symbols
>                   Ignoring extra symbols
Errors from xkbcomp are not fatal to the X server

(I've striped out many lines like this: I believe, there are irelevant to this 
bug)
