I wouldn't be surprised if most of the rotate drivers were broken
in CVS since the resize and rotate extension went in - the "nv" driver is.
But most of the drivers in 4.2.0 and 4.2.1 have support for rotate.
Grepping CVS source code shows ROTATE options in the following drivers:
chips and technology, cirrus logic, fbdev, cyrix, matrox, neomagic,
rendition, S3 virge, S3 savage, siliconmotion, trident, sis, nv.
Not sure which ones of those actually work though. Nearly all of
these drivers actually implement this in software so it's slower
than normal operation (no hardware features for the rotation).
