Oh weird! I didn't check padcfglock since it didn't happen to be
involved in the bug I was tracking down. I was trying to clean out
some skeletons in my kernel closet [1] and debugged it down to this.

If you want to smash the two patches together I'm fine with that. Let
me know, and CC me if you do post something.
