Okay, so
changing the scheduler to round-robin instead of FIFO had no effect. 
Neither did adding RT to the other FE thread(s)  or even giving X an
rtprio.  I can't seem to figure out WHY I'm getting all the
prebuffering pause messages.  Neither processor core is fully loaded,
XvMC is being used, storage is local on a dedicated XFS formatted SATA
drive.

I suppose I need to figure out what the message means.
;)  Is it that the FE has data but is being held up on rendering it,
or that it's waiting to render something, but doesn't have data yet. 

A promise:  If/when I figure out what the message means, and
possible ways to troubleshoot it, I'll write up a wiki to help others as
well.
