Why not boot into single-user mode, or runlevel 3, and run the
redhat-x<something_or_other>-config tool?

At the boot mgr screen, if it is grub, highlight your kernel, then hit
'e' on the keyboard to edit the kernel.  Highlight the kernel line in
the next sub-screen, and hit 'e' again.  Go to the end of the line
(usually after root=LABEL=/) and add a space and the number 1
(single-user) or 3 (no X), and hit return to end the edit.  Now type 'b'
to boot.

If lilo boot mgr, and it has a gui, click Control-X to get to a command
line.  Now hit tab twice to see your kernel options.  Type the name of
the kernel (2.6.3) as it appears in the list, but add the space and the
1|3 after it, and hit enter.

Now you should have a standard login screen (3) or a root shell (1). 
Run the redhat-xfree86-config tool to reconfigure X for your replacement
monitor.
