Thank you for your suggestions, it didn't quite do the trick though but 
might have put me a step closer.

I used your modeline/tried the new driver and the xorg log file states 
everything goes well and it's doing 1920x1200 @ 59,95 Hz.

No matter which resolution I override, the monitor displays a notice that it 
can't show the signal it is getting though. This suggest it doesn't like the 
frequency?

Any ideas for a next step?
