[PATCH] inivisible cursor on vesafb

Hi Linus,

Since vesafb was converted to the (strange) cfb* interface, it uses random
colors for the cursor, making cursor invisible when console uses black foreground
(f.e. Midnight Commander does that). Problem is common to all fbdevs which
use fbcon-accel interface.

This change tries to restore old behavior which existed before cfb* came in.
Unfortunately due to region.color semantic it is not possible to completely
restore previous behavior - 
+ for truecolor cfbfillrect always consults current palette, so we do not 
  have "always invert" constant available, and so we do inversion with palette
  color 15 (it is light white, ~0, by default)
+ for directcolor it assumes that display has at least 4 bits per color.
+ for pseudocolor it works as old code worked.

						Thanks,
