It does for me, but it puts the burden on Sam to re-apply his work on top of [yours+mine] (which is something he would have had to do anyhow to have his patches accepted, as he would have had to rebase on top of your series). I hope to find some more time to look into his series and find out how hard it would be to add his changes on top of mine, and hopefully help with this. Also, testing my patches with DVP would be nice (it should not be affected at all, but still...)
