smi501 support really doesn't belong in the same driver as the older
hardware since the hardware is substantially different.  The original
patch and the code in xfree86 cvs is a mess.

I was working on it a while ago, but at the time I didn't have
hardware, and since I got hardware, I haven't had time to mess with
it.  I have a driver available, but I wanted to test a bit more before
putting it in git.  Also, dualhead support wasn't working and I had
hoped to get that fixed.  However, I suppose it probably makes sense
to just put up.  single head works fine IIRC.

yes.  If you want to hack on the driver, let me know and I'll get the
current code in git and you can submit patches or have commit access
to the tree.

Everything is in git now.  cvs is basically just there for historical purposes.
