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. 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?
