OK, I have Xephyr.  Now I have lots of newbie questions.  First, my setup:

I am running the bulk of xorg from debian lenny.  I am running the 
nVidia binary drivers.  I've compiled Xephyr from git and installed the 
swrast_dri.so lib in /usr/local/lib/dri.  I am running the git Xephyr.

Xephyr starts up just fine. but I'm seeing some confusing behavior.

glxinfo tells me that I don't have DRI.  How do I confirm that xephyr 
was built with DRI?

mythtv and mplayer run fine using xv.  I thought xv depended on DRI?  Or 
do I have this completely wrong?

compiz won't run because 'Root visual is not a GL visual'. 

Is any / all of this because of the mixed nVidia binary and SGI glx 
server/client?  Or is it because I am running xorg 1.4 with the git 
(1.5) Xephyr on top?

Here's a partial output from glxinfo under Xephyr.
