Xorg.0.log

I have a primary CRT monitor connected to the DVI-0 port of a Radeon HD 3870
graphics card. To this card's DVI-1 port I have connected a flat screen TV
using a HDMI adapter. According to its manual, this TV is capable of running
1080i and 720p but xrandr doesn't show these resolutions:

    Screen 0: minimum 320 x 200, current 2624 x 1200, maximum 8192 x 8192
    DVI-0 connected 1600x1200+0+0 (normal left inverted right x axis y axis)
400mm x 300mm
       1600x1200      85.0*+
       1920x1440      75.0  
       1856x1392      75.0  
       1792x1344      75.0  
       1280x1024      85.0     75.0  
       1152x864       75.0  
       1024x768       85.0     75.1     70.1     60.0  
       832x624        74.6  
       800x600        72.2     75.0     60.3     56.2  
       640x480        72.8     75.0     66.7     60.0  
       720x400        87.8     70.1  
    DIN disconnected (normal left inverted right x axis y axis)
    DVI-1 connected 1024x768+1600+432 (normal left inverted right x axis y
axis) 640mm x 360mm
       1024x768       60.0* 
       800x600        60.3  
       640x480        60.0 

When I run the xrandr command, a list of modes (from EDID) is printed to
Xorg.0.log. When, for example, the 1080i mode that is printed to the xorg log
is added manually with xrandr, it works fine. But these modes aren't listed by
default by xrandr.

I'm using xserver-xorg-video-radeon compiled from git version 20110307.

I am attaching Xorg.0.log and the output of dmesg with the kernel option
"drm.debug=0xe" added.
