That patch set fixes my problems with vesafb. For the tested subset of 
possible
font dimensions and rotation values everything seems to be ok now. But maybe
someone with a  big-endian machine should also verify the code.

Isn´t it amazing that code as old as this still contains undetected bugs?

Is there anything like a framebuffer test suite that could be used for a 
quick verification
of especially the seldom used features?

btw: my favourite text editor sedt fails if the number of lines exceeds 
an internal
limit hit by rotation == 1 or 3 and small fonts, but it complains that 
it cannot read
its perfectly readable initialization file in that case ...  I wonder if 
there are more
applications like that.
