It could be a limitation of your monitor.  Pretty much every monitor
these days supports EDID (Extended Display Information Data??), which
means that the video drive or card card probe the monitor for it's
specs.  With this info in hand, X probably won't allow a setting that
would exceed the maximum specifications of the monitor.  You should take
a look at the X log - probably at /var/log/XFree86.0.log and you'll
messages from X about why it didn't choose a specific resolution.  Even
though it's not fully relevant these days, there is a HOWTO about 'X
Video Timings' that makes for a very interesting read over at tldp.org:
