I've just gotten a new Radeon based card, and I've been totally unable to set my refresh rate properly. It's really baffling, because according to amdcccle, my monitor (Acer 1916W) is capable of 1440x900 with 75hz refresh, and it used to do that just fine with my old integrated NVidia solution. My new radeon, however, just won't work with that refresh rate.
Here is the section from xorg.conf:
If I run amdcccle, the digital monitor shows up fine, as "AL1916W", with a maximum refresh of 75Hz. If I try to change it on the display manager portion of the control center, my only options are 60Hz and "preferred", which I suppose is code for 60Hz.
Any ideas?

Any ideas?
