Oh good question, at the moment no, and I probably need to block rotation on slaves until it is I suppose. The problem with transforms at least for the intel LVDS slaved to the nvidia, is the nvidia pcopy engine can't do transforms, and we definitely want to use it for copies if we can. For USB devices it should be a lot easier to hook onto the rotate code, if still a bit messy.
