Works for me.  I even have that same monitor though I think it's running
off the VGA port -- I'm using the DVI to drive a Dell monitor at the
same resolution, and -- I think -- frequency.  I'm away from my dock for
the next few days so can't check.

I'm currently using the latest fglrx shipped by ubuntu.

  $ dpkg-query -l xorg-driver-fglrx xorg

This version of Xorg apparently uses some newfangled config system where
lots of things don't go in xorg.conf, but mine is enclosed.
I use xrandr to change resolutions.
