I came to think of a few pieces of additional information that might be useful for the upstream developers. They might ask for it, but you may also upload it right away:
1. Kernel Mode Setting is now used in Karmic, so it is actually a kernel module that takes care of selecting the resolution. This code has been ported from the intel driver. It is possible to switch back to Userland Mode Setting (UMS) by adding this the boot parameter i915.modset=0 when booting. The code in the intel driver will then be used to set the resolution. This should select the same resolution as with KMS, but unlike the kernel module the intel driver dumps extra information to Xorg.0.log when the ModeDebug line is present is xorg.conf (as you have). So if you could boot with UMS and attach the resulting Xorg.0.log and the output of `xrandr --verbose` that may be valuable information.
2. You report that this happens when you use both the internal laptop monitor (LVDS) and the TV as an external monitor. Does it also happen if you disable the LVDS? You can do that by adding the following section to xorg.conf:
Section "Monitor"
      Identifier "My internal monitor"
      Option "Ignore" "True" 
EndSection 
and the following line to the "Device" section:
     Option "monitor-LVDS" "My internal monitor"
(with KMS it may be "monitor-LVDS1", but I'm not sure...)
