Problems with latest Xorg/mesa/drm/Intel git (G33)

[Vincent Vanackere]

Hi,

Since the merge of the branch 'buffer-objects' in the intel drivers,
the xserver on my Intel G33 integrated chipset exhibits the following
problems :

- the mouse hardware cursor looks weird (screen corruption around the pointer)
- the xserver crashes when trying to use xv

I'd like to know if those problems are known/worked on : both problems
occur with EXA and XAA. Latest working combination was for me :

 drm (lib + kernel module) : 20070919
 mesa : 20070920
 xserver : 20070921

A debug trace for the Xv crash follows. I can provide more information
if necessary.

Best regards,

Vincent
