Can't get 1280x960 nonstandard resolution on xorg (fglrx)

Hi, I've recently installed Arch Linux on my machine and I must say that I'm impressed with its simplicity, speed, and even pacman's ability of removing unused dependancies.

I've managed to properly install fglrx with affirmed direct hardware rendering, and I'm using KDE as Desktop Environment.   However, I'm having a problem getting my 1280x960 resolution on xorg.   I've had this problem before when I used MEPIS, however it was fixed it by adding a manual modeline since it was a nonstandard resolution.  Unfotunately, that doesn't seem to be working in Arch.  The "NoDDC" option doesn't seem to work either with the modeline.  Can anyone help me figure out this problem?  1600x1200 is killing my eyes on my 19" CRT and 1280x1024 makes recangular pixels.

Thank you
Rob

I've reviewed the ModeLine trick again, but it doesn't seem to work anymore.  Does anyone have the same problem?

No, unfortunately it's not in the list.  :-(

This is odd, I'm just wondering if it's due to a change in xorg, or the fglrx driver...
