This is what I have suspected all along is that the signaling and timing
constraints on the PRI are such that you basically need asterisk running as a
real-time process.  The whole point of the thread (in my mind) is if there is
anyway to cause X to not run as such a real-time process so as to allow
asterisk the proper access to the hardware that it needs?  and why can I run X
(as in Xvnc which starts x servers) without any problem? but not a real x
server?
