The code is in the branch, but its really ugly, I was hoping to actual do it cleaner which might involve a new kernel interface to ask for the current placement of a buffer object so we can decide whether to just memcpy or we need to blit for DFS. I'm not sure I saw a good reason for UTS, doing Host data blits isn't really useful with BOs at least with the current code.
