turning off xdm?

[Bob Koss <koss@objectmentor.com>]

I upgraded my potato install to kernel 2.4.7. When I rebooted, I was
greeted with a graphical login. 

How can I go back to booting to a shell prompt and then starting X if
and only if I want to start X?  All of the runlevels except 1 seem to
have xdm. Should I just pick a runlevel and delete the xdm in the
corresponding rc.x directory?
