The xorg.conf file can say anything it wants, but
the X server can have its own reasons for
deciding to ignore it :-).

Sometimes you can dig through the cryptic gibberish
in the /var/log/Xorg.0.log file and see why the
server rejects some modes. Possibly something
like adding vertical and horizontal refresh
info to the xorg.conf file will convince it that
it is OK to use a mode it rejected, possibly
you need to generate a mode line and cram
it down xorg's throat :-).

There is a program that comes with X these days
named "cvt" which can generate valid mode lines
that might work.

Some of my own experiences with different versions
of X can be found here (though the X server has
changed a lot, so not everything is relevant
any longer):
