Re: 2.5.51 -- rivafb is whacky (characters flipped on vertical axis, 640x480 usable area shown inside a higher-res area, etc).

James, I appreciate all your hard work.  I hope my bug report
isn't too upsetting for you.  I think you are making great progress.
It is also a shame that so much of the driver porting has fallen
on your shoulders.  If I were a programmer.  I'd help, but my skills
are in software testing, for the most part.

All the best,
	Miles
