Replying to myself...
Problem solved. It turns out that I didn't transfer my DisplaySize
setting to the new Monitor section in my xorg.conf. After doing that
it appears to be working very well.
FWIW, I just added:
DisplaySize 225 170
to the Section "Monitor" for the component video monitor, which is
what I was using with the svideo connection.
