I have the same on my HP dv8220ea with an Nvidia GeForce Go 7400. But a fresh install of Ubuntu 6.10 (Edgy Eft) uses the correct resolution of 1440 x 900.
In Ubuntu 7.04 (Feisty Fawn) Herd 1, Desktop CD, live session, the screen is incorrectly set to 1024 x 768.

I suspect this may be caused by bug #78315
Let me know if you want me to get some files off the machine, I won't risk an install, but I should be able to get them from the live session.
