That was the problem, I enabled dynamic twinview and the problem was fixed!

I believe I set that to force X to use EDID modes.

You have no monitor section (no vert/horiz freq ranges)

I use X's autoconfiguration, since I know my monitor is detected correctly
(I figured that out when I originally set this it up).

Anyway, DynamicTwinView was the problem, once I enabled it the problem was
resolved. I'm not sure why that worked in the older driver and not now. I
didn't want to go back to the old driver because I was tired of the HDMI
audio always breaking when X restarts.

Thanks for the help everyone!
