This is the modeline that should be used, taken from my actual config file:
# 1280x1024 @ 56.00 Hz (GTF) hsync: 59.25 kHz; pclk: 101.43 MHz
Modeline "1280x1024" 101.43 1280 1360 1496 1712 1024 1025 1028 1058
-HSync +Vsync
It seems that I have generated it with 56 Hz in mind - could this maybe
cause the trouble? Is there anything wrong with the line, I have
generated it with "gtf" in "-x" (xorg) mode?

Andreas
