I was able to reproduce it on my Compaq EVO with Radeon Mobility 7500.

In 8bpp everything works correctly. In 32bpp "clear" immediately fills
screen with blue instead of white (if I get it correctly, it is actually
not clearing with blue: it clears with $CORRECT_BACKGROUND & BLUE).
In 16bpp it behaves randomly: sometime it clears with correct color,
sometime with $CORRECT_BACKGROUND & BLUE... Strangest is that going
with up arrow through bash history causes bash line displayed on essentially
random place - left to correct position, sometime even so left that it
is displayed on right side of screen one pixel up.... (I did not notice
this problem with 8/32bpp; 'fbset -accel false' has no impact on
behavior)

Only thing worth noting is that it is on kernel with my matroxfb patches...
I do not know whether Jurriaan uses stock kernel or my patch.
