OK I had gentoo back in March and had this problem, after getting a new hard drive for a while I didn't install gentoo. I installed gentoo again and have the same exact problem.
The resolution in XF86Config-4 does not stay. OCCASIONALY I will get the right resolution. It will always use the right resolution if the computer has been off for a long time. Sometimes it will work if I change any random setting in XF86Config-4 and restart X. But this will only work once. If I logout, restart, or shut down I get dropped to 640x480. After that I have to wait a long time with my computer off if I want to get the right resolution!!! This has absolutly been driving me nuts! It's like a voodoo curse on my box or sumthing! Has this never happened to anybody before?!?
