Yan, thanks for the suggestion.  I will have to check it out.  Losing
XvMC and compiz are not issues, as I am currently using neither.
However, if it affects the KDE (kwin) desktop effects then it is a
deal-breaker as that is what I am trying to get around.  Also, I've
looked at some of the other multi-seat setups, and they all seem to
assume multiple graphic cards, as opposed to a dual-headed card, and
also require a separate keyboard and mouse for each display, which I
don't have.

Allan, thanks for posting your xorg.conf.  This almost exactly matched
my current setup.  I made a few tweaks based on your post, but I'm
still not getting it to work properly.  Yes, I can get the frontend to
display on the HDTV like I want, but when I switch mouse and keyboard
control back to the primary display I can't figure out how to return
them to the MythTV display when I need to.  What am I missing here, or
is this simply the way it works?
