Ok, here's the full configuration snipet and some explanations.

1280x1024 modeline is advertised by your monitor. See the xorg log for 
the full modelines list from your monitor.
The 2 other modelines have been generated by 'cvt 1280 800' and 'cvt -r 
1280 800' respectively, they are needed because not provided by your 
monitor. The 'ReducedAllowed' option is added to allow the monitor to 
use the reduced blanking modeline (1280x800R).

The Modeline lines are actually not wrapped, this is a mailer artifact.
Lemme know if it works, and if not provide the xorg log.

btw, your web server seems down atm.
