I had this problem, though with an ATI integrated graphic card and a 
"normal" LCD monitor: the resolution I wanted was not available in the list.

I had to specify an according modeline in my xorg.conf file, and afterwards, 
it worked.

There are plenty of examples on the web, and even sites that "compute" them 
for you, here

http://bohne-lang.de/spec/linux/modeline/

and

http://xtiming.sourceforge.net/cgi-bin/xtiming.pl

for example.
