Am now making some progress on the mangled graphics: When i have acceleration turned on, glyph drawing is a complete mess. it looks like the bits are being expanded backwards and characters are being read from the wrong place. I've gone through CPUToScreenColorExpandFill with a fine tooth comb, but can't see anything wrong, and all my MMIO_OUT32 writes into BRxx are correctly expanding into xf86WriteMmio32Le.
Have you ever seen anything like this before?
