Hmm, oh well.  No idea how to test it then, other than hard coding 32bpp
in the offb.c overriding what it gets from the firmware.

Still fixing the reversed red/blue would be nice.

Does the radeonfb have the red/blue reversal problem in pseudocolor mode
(I think that's what it came up in too by default)?
