Well, it's i8xx in general that's in a very sorry state with gem.
Unfortunately there's no easy fix available, even within intel no one
knows anymore how to work-around these problems (hw people designed these
chips approx 8 years ago and moved on). I have ideas that might fix these
problems. Unfortunately this requires rather massive code rewriting. But
I've been (very) slowly moving towards this in the past few months. Don't
hold your breath, though.
Meanwhile Chris Wilson's shadowfb support should give you Xv accel +
reasonable fast 2d (cpu-rendered, but the gpu was never really faster for
2d on these chips, anyway).
