An ATI X1250 can't handle HP LP3065 display at 2560x1600 using a dual-link DVI cable on Ubuntu Karmic.

The display remains limited at 1280x800, returning:

(II) RADEON(0): Not using mode "2560x1600" (mode clock too high)

The connector on your PC is HDMI-A though at least according to your log.  If the connector on your PC is not HDMI-A, then let me know.

Ok, I talked to Daniel and the system actually has a DVI port rather than and HDMI port.  I've added a proper quirk:
