Ok, I see your problem. The preferred resolution is currently defined by the following entry in monitor section:

Option “PreferredMode” “1400x1050”

You screen section has highest resolution defined here:

Modes “1400x1050”

You will probably be able to solve this by changing monitor via sax2, oredit xorg.conf manually if you are up to it.

Post back if you require further help.
