Subject: Bug: i915 3D performance degradation after suspend-to-ram

Hi.
With Linux 2.6.31-rc6-git7 I see some 50% 3D performance degradation
after a suspend-to-ram cycle. I normally use only two 3D apps:
glxgears falls from 591 FPS to 400 FPS and stellarium from 19/20 FPS
to 12/13 FPS.

The hardware is an eeePC 900 (915GM) and userspace is updated (xserver
is 1.6.3 and the intel driver is from git tree).

I don't think this is a regression.
Regards,
Fabio
