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?

Regards,

Andreas
