Andrew, thanks for the tip.  I patched my kernel with Ruby, but it 
wouldn't load the nvidia drivers.  I gave up after that since I'm mostly 
expirementing right now.  It did have the devices registered separately 
though in /proc, so it was definately working.

However, I still think there's got to be a simpler way to do this... I 
found out that I can open xterm on display :0.0 and run DISPLAY=":0.1" 
mplayer movie.avi which will play the movie on my TV.  When my wm focus 
is in the xterm, any keys I press and remote events will control 
mplayer.  So, in my limited knowledge of things, it seems to me that it 
must be possible to somehow get this working if I could setup my remote 
(since that's all I want to use to send events to the TV's X display) to 
prepend all commands with DISPLAY=":0.1" ${1}.  Maybe with lirc?  I 
haven't looked into that much.

I tried running freevo in xterm on my first display, and that wouldn't 
accept any keypresses, so I don't know what the difference between that 
and mplayer are.  I havent tried any other programs yet, so mplayer is 
probably the exception and not the rule.

Anyway, the bottom line is I wish X was a little more flexible with 
input devices.  From what I understand, any events inputted get sent to 
all the terminals attached (or something).

I'll just have to keep playing around to see what I can come up with.
