There used to be a vesafb problem with MTRRs when the framebuffer had an odd size: 2.5MB of RAM (my laptop has this).
It would create an MTRR for the first 0.5MB of the framebuffer, and then try to create another for the subsequent 2MB.
The latter failed because it's not suitably aligned - i.e. there was a problem in th logic which splits non-power-of-two regions.
Is that fixed these days?
