Thank you for the clarification on set_mode_major.

The driver api breakage isn't "necessary", but is an attempt to clean up the 
usage.  It seemed to me that the only reason the rotation parameter was needed 
was so that the set_mode_major function could explicitly process the rotation 
transforms, which is something the xf86CrtcSetModeTransform() function does 
already (and was being skipped without this patch).

transform processing with KMS

set_mode_major is not exclusive to kernel modesetting.

Is the driver api breakage neccesary? If so you definately need to
bump something somewhere.

Maarten.
