there are a few. One is http://www.nyditot.com/home.htm. You get full control (resize and rotate)
Another is http://www.jimmysoftware.com/NL/Landscape3/index.html
Have to pay for both, I think nyditot has a demo period.
The other FREE one is pocktop keyboard driver
They have it for the Axim as well (I used it for my Toshiba e750)
It shows up as a input device (lower right corner) So open up note or word, choose the pocket top keyboard and a toolbar pops up. click on the rotate icon and rotate it any direction you want.
