There are a few issues with getting such devices work with X, but it is
possible.
1. You probably need a DVI→HDMI adapter in all cases, since these
devices refuse to display 1080p with a VGA cable (you know, security,
DRM, blahblah, LOL).
2. I guess it depends on the TV, but mine requests 1080i through EDID
and X doesn’t really understands what this means. It generates a
1920×540 modeline in this case, and of course this doesn’t work.
3. X-generated modelines are meant for CRT or LCD monitors, not for TVs
which need much lower synchronization times.
4. X prefers using its own modelines even if you specify others by hand,
so you have to specify another mode name.
The result is the following configuration:
Section "Device"
Identifier "ATI Radeon trucmuche"
Driver "ati"
Option "IgnoreEDID" "true"
Option "Monitor-DVI-0" "Configured Monitor"
EndSection
Section "Monitor"

Modeline "1920x1080_p" 143.64 1920 1944 2040 2128 1080 1082 1085 1125
Option "PreferredMode" "1920x1080_p"
EndSection
Section "Screen"

Device "ATI Radeon trucmuche"
DefaultDepth 24
Subsection "Display"
