We've had exactly this problem. Replace the "nsc" driver with the standard "vesa" driver. The configure program sometimes incorrectly identifies the geode graphics engine. We never got to the bottom of it and now that AMD have taken over Geode from National (who took it over from Cyrix) I don't hold out much hope of it ever being fixed. AMD have there own embedded processors and the GEODE was a competitor. Which chips do you think AMD will put the support effort into. Also I'm a bit worried by the refresh rate you are driving the LCD at. Most work best at around 50/60 HZ. Suggest you fix on the optimum refresh rate for your LCD and just have that rate specified in your XF86Config file.

I am trying to get a LCD display working, and am running into problems with X. When I start X windows, the LCD display goes blank. When I exit X, my LCD display comes back. I have checked, and my kernel was built without APM_DISPLAY_BLANK set. The display is 6 1/2" diagonal and the resolution is 640x480. Does anyone have an idea what the problem could be? What can I do to further diagnose this problem?
