http://www.nyditot.com -- this is the screen utility I have on the axim, it's quite nice, it can rotate or do virtual resolution, and be either pan-and-scan mode, or compressed. (you can toggle compression and rotation in real time, but to change the resolution, you need to do a soft reset, OS limitation) It also has the ability to change and skin OS fonts and colors etc.
You can, however, get a wireless keyboard driver for free if all you want is rotation.
