LinuxQuestions.org - Screen scolling problem / resolution issue?

Hi. This problem suddenly raised it's head after I had installed the Radeon drivers from the ATI site.

I have a Radeon 9200, and have managed (i think) to get it working.. at least HardDrake seems to think it is.. My major issue is that I can't seem to fit 1024 screen resolution on my monitor - I get a scrolling effect, both to the right and downwards. I know the monitor supports 1024 (a Samtron 55e, it's set up as plug'n'play).

It's almost like something thinks that my resolution should be 800x600 (which fits fine)

Any help would be gratefully accepted (bear in mind I've only been using linux for 1 week now)

Here are the relevant sections of my XF86Config4 file:
