Got the Netwinder to change resolutions and run the xserver-fbdev without core dumping. Thats progress. (fbset -rgba 8,8,8,8)
Now if I could just find a decent monitor. My choices thus far are a fixed frequency 640x480 9" monochrome, a focus blown 13" color, and a NEC 3FGe which doesn't want to sync above 800x600 and loses the red gun sporadically.
