[CALUG] How do I get out of X?

[Edward D. Browne]

Hmmm, guess I haven't needed to do this since quite a few
releases ago.  I'm trying to upgrade my graphics driver
(to NVIDIA-Linux-x86-1.0-8762-pkg1.run), which means
I have to get out of X.  As I recall, there was always a menu
option at the login screen to log in without X running, but now
with RH AS3, I see no such option.  Killing X, and everything
that looks connected to X, only results in it automatically
restarting.   init 3 or 4 or 5 or 6 (it doesn't seem to matter)
just causes the machine to reboot all the way back to run
level 6.  What obvious solution am I missing?
