[PATCH] I was wondering why I can't set the resolution to 2560x1080, while in windows 7 I can without a problem. I looked at the radeon driver code and found it doesn't support this resolution. So I made some changes. I added the hdmi_mhz parameter. In cmdline I set radeon.hdmi_mhz=190 Only tested on the Radeon HD 5830
