Same problem with kubuntu gusty beta on an inspiron 6400. I have a resolution of 1400x1050 instead of 1680x1050.
I try to add this resolution to xorg.conf, but it didn't work.
The only way to add the good resolution is to install the restricted driver, but I have other drawbacks (mainly Kaffeine crash, bug with video...)
