[Intel-gfx] Screen corruption (especially) after resume from STD on GM965

[Stefano Avallone]

Hi,

I upgraded libdrm, mesa and xf86-video-intel from git master yesterday. I am 
running kernel 2.6.29, UXA, no KMS on a GM965. After a fresh boot, I noticed 
some glitches but continued working. After resuming from a suspend to disk, 
the graphical corruption increased to the point to make the system unusable. 
You can find a screenshot here:

Then, I reset my local xf86-video-intel git repository to commit "Disable LVDS 
config parser from VBT from now", i.e., the commit prior to "Tiling fixes, 
third set". After a suspend/resume cycle, I was not able to produce any 
corruption.

Find attached my xorg conf and log. If you want me to do more testing, just 
let me know.

Stefano
