Dual head second monitor resolution problem ATI Radeon Mobility 7500 Redhat 9


I am using a ATI radeon Mobility 7500 video card with redhat 9 kernel 2.4.20-31.9 and after trying for quite a long time I finally got the dual head to work on my video card. However now I have another problem. I cant get the resolution of the second display to be anything other than 640x480. I know that my video card supports higher resolution on the second display because I can go much higher when using windows. Any help would be greatly appreciated. Here is my XF86Config File.

Thanks For the help.
