This seems to be based on a somewhat older codebase; I tried to be careful while adjusting the patch to the current codebase, but please give it an eyeball to see if I didn't make any silly mistake in the version that has been parked on 'pu'. After an positive Ack (or you botched the forward-porting; here is a rebased one you should replace them with), I'd like to merge it to 'next' and then to 'master' by -rc0 (or -rc1 at the latest) so that we have enough time to expose the updated code before 2.0.
