That branch booted fine for me and didn't show any problems.

I wasn't easily able to merge onto linux-next and test there though.
I tried applying these the 4 top commits of your branch to
"next-20130408" and it didn't solve my problems.  A full merge of your
branch to linux-next showed conflicts and I didn't dig.
