What you describe (320*480 portrait) can be seen in the 5.3 Simulator from PalmSource.
Are you sure you are using the T-T3 Simulator which can be downloaded from PalmOne, not from PalmSource?
In the T|T3 simulator I downloaded from pluggedin.palm.com on Friday, I am able to switch orientation using the same button press as you'd use on the real device.
