Sounds like an endianness problem. It looks like the glint driver doesn't
address this indeed. Does pm2fb work? If so, does Option "UseFBDev" help?
Otherwise, you'll have to find out how to enable byte swapping for the
framebuffer, either by using a different aperture or by setting some bits
in some register.
