Comment 81 for bug 431812

i have a q1 ultra and i couldn't even install 9.10 without using the modeset trick, as it just kept flashing that 22 error. correct me if im wrong, but does using i915.modeset=0 disable whatever form of acceleration the graphics card had? i ask this because i noticed that anything that would normally appear to use acceleration seems to run incredibly sluggish almost to the point of complete lockup.
