ATI + LCD Monitor - refresh rate problem

[Moshe Bergman <debuserslist@moshebe.no-ip.com>]

Hello,

I've been trying to get linux to run properly for a week or two, so far 
i've managed to install ATI drivers, however I still have one problem - 
refresh rate.

On windows my monitor runs fine on 75hz, Hsync: 79.9 and Vsync: 75.
However, on Linux, it does not seem to matter what i enter on 
XF86Config-4, the monitor is still set to 60hz.

I have ATI Radeon 9800, and Hyundai ImageQuest Q17.

Thanks,
Moshe Bergman.
