You know, I disabled Nvidia's DDC stuff and enabled firmware EDID
again and it started working fine, even without
video=nvidiafb:1600x1200MR on the command line that I had for a long

So it works fine now. Would you oppode adding dmi check for inspiron
8100 to automatically disable nvidia i2c support at runtime?
