It was my impression that the RandR extension (introduced with XFree86
4.3.0) has the ability to do this. However, it has to be supported by
the driver. On my Radeon M6, it is not. The output of xrandr shows:

Rotations possible - normal 

So, no rotation possible. If you run it on hardware where the driver
supports rotation, the xrandr output would look like this:

Rotations possible - normal left inverted right
