However, the reason is known: the fbcon-* code draws the cursor by xor'ing the
pixel values with a mask consisting of all 1's. This is not correct for
directcolor modes (e.g. 16, 24 and 32 bpp on ATI Mach64), where the color of
the cursor depends on what leftovers are present in the palette registers.
The fix is to make fbcon-* use a mask in the 17th entry of
display->dispsw_data[], and to make drivers fill in this field where
appropriate.
