Well, get-edid complains about an invalid/incomplete EDID, and back
when I was using this with an ATI Radeon 9000 via DVI-to-HDMI cable
it, similarly, failed to deal with this EDID. I've been convinced
since I bought it that this set was outputting broken EDID, and was
surprised enough that it gave any at all for that matter (early
HDMI-supporting rear-projection 16:9 HDTV). Up until recently my
only option had been to disable EDID querying and force specific
modelines in xorg.conf (or hack the mode I wanted into the kernel
default timings and use fbdev), but more recent improvements in Xorg
have at least made it so all I need to do now is toss a few lines in
my .initrc, so I'm not complaining. ;)

I might not have been clear enough in my description here. I've
actually broken into the "secret" Sony service technician menu on
this set to readjust the picture inward so there is no overscanning
for the modes I use. What seems to be happening here is that the
kernel believes the 720x480 mode the TV advertises in its EDID
block, but the television is then throwing away the left and right
40 pixel columns (leaving wide black "pillar box" bars in their
place) to trim the width to 640 pixels, implying it thinks that 480p
is only a 4:3 aspect format. Its 640x480 mode occupies the exact
same region of the screen. Definitely can't blame overscanning for
this one, I'm afraid.

No mention of the string "not using" in Xorg.0.log:
kiosk at hastur:~$ grep -ci "not using" /var/log/Xorg.0.log
0
I'll include all the intel(0): lines from the log after my .sig, in
case they help.

Ahh, so interlacing *is* supposed to work? I had tried adding a
bunch of ATSC standard interlaced modes the TV appears to support
from other consumer A/V equipment, but was never able to get the
driver/chipset to output anything the TV felt like displaying.
