Some further info:

I reinstalled from scratch today, wiping everything but my /video 
partition.  Followed Jarod's guide all the way up to the 7174 nvidia 
drivers, with just a monitor attached, no transcoder or TV, and using 
Jarod's xorg.conf unaltered.  The same thing happens with the monitor.  
Furthermore, the other two modes in that modeline result in a virtual 
desktop.  This did not happen with the 6629 drivers.  I'm at a loss, and 
have no easy way to get back to a working setup until I figure out the 
problem.

Digging around on Google, I can't find any references to anyone else 
with this problem.  I'll have to dig further, it seems.

Jeff.
