Well, something "interesting" is certainly going on because our 2.6.11.7
kernel *does* work and *does not* crash when running user space
applications.  It runs BusyBox quite happily with multiple processes
(e.g. 3 incoming telnet sessions, a console shell, etc.).

I can only conclude that there is something more to our 2.6.11.7-based
patch than I currently understand.
