So I've put these patches into Fedora rawhide kernel to test, and
glxgears on my
945G hw went from 85fps to 380fps, clearly we would want these patches
upstream sooner
rather than later.
Or we at least need something in the i915 driver to get the speed
under GEM back up.
I'm happy to ship these patches in F10 GA if that makes any
difference, so I'd really like them upstream asap.
Dave.
