On my 760ED (1024x768 matrix) following modeline
works without any problem:
Modeline "1024x768" 70.00 1024 1076 1212 1332 768 771 777 806 -hsync
If XL model has 800x600 screen, you'll need another modeline,
Unfortunately, guy who owns 760C is not in office now and I cannot
cite his modeline. But VESA standard modeline should work.

Start xvidtune and try to adjust parameters interactively. (run it from
xterm, so when you press Show button, modeline would be visible on screen)
Open /etc/X11/XF86Config in nearby window and copy modeline, printed
by xvidtune there.
Make sure that there are no other modelines in your XF86Config,
especially modelines with same name. String "1024x768" in quotes is
modeline name, which doesn't need to be "XxY" - I often use "XxY@Hz",
and you even can write "my beloved mode". Just make sure that
same string is specified in the Modes line in Screen section.

xvidtune is your friend.

X-Window just have issues with improperly written configuration.
I've never experienced problem with any thinkpad I was able to lay
my hands on.
