The gma500 is basically undocumented. Although its on Intel hardware it's mostly an imagination device with no manuals. The driver was built out of the pieces that were used with a proprietary user server without documentation.

If you boot with all the drm debug turned on then it may give us some clues, but probably we can't fix it.
