So far so good (I would have tried earlier but turns out a PCI-E
riser in my system was silently disabling/overriding my HDMI
interface). I'm only effectively able to test 640x480 to my HDTV
because I suspect the driver needs an EDID quirk for it. With an ATI
Radeon and a DVI->HDMI cable I was successfully using:

Section "Device"
   Identifier      "ATI Radeon 9000/RV250"
   Driver          "ati"
   Option          "IgnoreEDID" "on"
EndSection

Section "Monitor"
   Identifier      "Sony KDF-60XS955 HDTV"
   HorizSync       15-46
   VertRefresh     59-61
   DisplaySize     320 180
   Mode "1280x720"
      DotClock  74.25
      HTimings  1280 1320 1376 1650
      VTimings  720 722 728 750
   EndMode
   Option          "PreferredMode" "1280x720"
EndSection

Key here is that I have to override EDID checking because this HDTV
only claims support for 480p and 1080i for some reason, but its
native resolution is actually 720p. Trying IgnoreEDID (or NoEDID for
the DDC module) with the intel driver didn't keep it from believing
EDID according to the log, and I see in the list archives that
adding a quirk in the driver is the preferred solution anyway.
Should I file a bug report requesting this? Granted, the timings I
used are probably not optimal as I had to recenter the image through
my television's service menus. Here's what my EDID looks like:

Your EDID is probably invalid.
