No, IIRC that's exactly the one it assumes you have if you're running
As I said, the driver assumes the register aperture is big endian with
Option "UseFBDev". And without, it will also try to use the big endian
If there's really no way to use the big endian aperture on some boards,
the only solution I see is to change both pm2fb and the glint driver to
always use the little endian one.
