FWIW,  I'm working on an X driver for the smi501 chips as well.  It
supports XAA and purports to support dualhead although at the moment,
I can't get crtc2 to actually display anything other than the hardware
cursor.  Although up until just recently I didn't have any hardware to
test with.  I'm wondering if there is some FB enable bit somewhere
that I'm missing, or if perhaps the smi501 is like the lynx chips and
the framebuffers for each crtc have to be contiguous and fit into a
single accelerator surface, however Vincent's patch seems to indicate
otherwise.  Any thoughts would be appreciated.

Attached you will find a first cut of a driver for the silicon motion
SM501 mobile multimedia companion chip.

Good to see, I was working on the SM501 also for a while and
I am looking now to get it into the kernel, too.

The driver actually breaks down into a "base" driver for all the
available functions and a framebuffer driver for the video elements.

What is the status of your development? Did you push it upstream already?

Comments and patches gratefully received, I don't know how much more
complete a driver has to be for consideration for mainline merge but
that is the ultimate aim.

Any help needed? Please give me an update about your progress.

Best greets,

Clemens Koller
