>From your Xorg.0.log:
(II) RADEON(0): Output DIN disconnected
(II) RADEON(0): Output VGA-0 disconnected
(II) RADEON(0): Output DP disconnected
(II) RADEON(0): Output DVI-0 connected

DIN: S-video?

Clearly your working monitor (DVI) is on output DVI-0.

What is the actual card you have? (manufacturer, model)
List all of the connectors that it actually (physically) has.

I can think of a few possibilities:
1) That the DVI and HDMI plugs are wired into the same place,
2) That the HDMI plug is on the DP (or you are actually using a DP-HDMI cable)
and you suffer from a similar defect as my mainboard:

If you have BOTH an HDMI plug as well as a DP plug on your card, then I would
guess option 1 and you will need to pick up a passive DP-HDMI adapter cable to
use the second monitor. If there IS NO DP plug, then I would guess option (2),
in which case you'll have to hack the kernel to make it work or beg someone to
add a workaround for this defect.
