Really? Do the Intel Macs have a different version of Mac OS X from the one you're using? I was playing around with the Intel Mac Mini at the University store, and found it quite trivial to get the screen to rotate, though the LCD that was attached viewing angle wasn't too good rotated 90 degrees. The only problem was the disconcerting amount of time the screen was black before rotating. Even the movie trailers played well with the screen rotated, which was surprising.
