I restarted the box and repeated the sequence using Xftree.  Sure enough it locked again and again.  Thankfully, ext3 recovered each time.  I started Gnome and found that I could repeat the problem.  KDE did the same thing.

Update:
No screen lock-ups since building new kernel two days ago!!  
I have switched between 8-but, 16-bit and 24-bit and the machine is rock solid while doing the things that caused it to freeze with Red Hat's kernel.
