Hi Belcon,

    This code looks very much like the sm501 code smi submitted a few
years back.  As Clemens mentioned, I've taken that code and removed
the support for the old vga chips and started a git repo for it:
http://cgit.freedesktop.org/~agd5f/xf86-video-smi501/
I even added dualhead support, however, I was never able to get it
quite working.  I was not able to get the panel to display anything
but the cursor when both controllers were active.  Perhaps you could
take a look at it and use it as the base of your sm501/2 driver.  I'm
am happy to help out however I can.
