  Thanks Alex,

  I made some tests, using your driver, and xorg driver, but neither
did work. After that, I borrowed some changes changes from the
siliconmotion 2.2.5 sources to your smi501 sources (as this is the
hardware I can test), and almost got it to work (added 1024x600 mode
support, but I think it is required to add some extra PLL programming)
to get it right; at least with these minor changes it doesn't stay in
a black window anymore...

  Anyway, I think it should be merged to a common source, probably
by siliconmotion engineers, or at least someone that has knowledge
and access to all the hardware variants.
