I discovered the problem.

Please close this "bug" report 542069.

The connector at the monitor attached to TMDS-1 was seated well enough
to produce a video signal, as I saw at boot time.

Apparently, however, it was *not* seated well enough to provide the EDID
data.  I must have moved the monitor last week and disturbed an insecure
connection to produce my problem.

After reseating the connector, all is well.  I'm running the latest
unstable stuff right now.

By the way, after I restart the X server, I have to toggle via
CTRL-ALT-F1 to the linux console and then back (ALT-F7) again to X
windows in order to get my TMDS-1 screen to be fully accelerated.  If
anybody who sees this knows why, then please shoot me an e-mail.

Obviously, I have a manual work-around, but I'm interested in an
automatic work-around.
