From the silicon motion homepage you could get a framebuffer driver
for the SM501 PCI card. This should work without great
modifications for PPC systems.

Thank you, I know that thing. I started with that driver, but I did
quite a lot of code cleanup (I guess there are lots of leftovers from
the SM7xx parts). I am about to put this into a loadable
kernel module fbdev driver.
Later on, we might need some power management, use it on
different resolutions and use the other on-chip peripherals...

Oh, sounds interesting. We took the driver from SMI and hacked it
to run on our board. Three different resolutions are possible:
640x480, 800x600 and 1024x768. We use "fbset" to change it.
But with the higher two resolutions, the picture is very noise.=20
I think this is because of two high SM501 internal memory clocks.
Unforunately the datasheet of the grafic controler is very spare -
not to say poor. So I yet couldn't figure out, at wich speed the
memory clock is running actually and how to change it.

Do you use any of the other peripherals of the SM501, too? (USB,
Audio, 8051)=20

No, actually not.

Regards,
Martin
