I was hoping to be able to reproduce this on the 845 mtp (I don't have a db845), but I can;t seem to get venus working on mainline [1] (neither with linux-next, nor with linaro integration) Do you know if I might be missing some fix?

Sure, I'll send a patch for that and see what the rpmh owners have to say.
