Hi Adam,
It seems a lot of people aren't too thrilled with the i810 driver in Xorg.
I had a problem of direct rendering being on but alternately giving me 300+
fps on glxgears and then 30 fps after logging out and logging back in.
Anyway, after much searching, I found this link:
http://www.fairlite.demon.co.uk/intel.html You might try downloading that
driver, and see if it fixes your problems. It's worked for me, and a few
other people as well.
Note that for X, use the i810_drv.o driver (called i810 in the config file),
but in your kernel, load the i915.ko driver.
If you want, post the relevant portions of your log file, and we'll see if
we can't figure out what's wrong.
Best of luck,
Justin Guerin
