The fillrect() for arbitrary bitdepths is in fbtest now. I also added fast
support for planar screens. Well, now I can start porting amifb to the accel
framework.

So far I tested fbtest on
  - PPC (atyfb on 3D RAGE II+, cfb)
  - m68k (amifb on Amiga AGA, planar)
  - Alpha (tgafb on DEC UDB with 8-bit TGA, cfb)
