odd, that's what I tried (just rebuilt from the .spec).  I got:

  "Exception starting xend ((13, 'Permission denied'))"

starting xend, which I read is the common error message on version
mismatches. I reinstalled the 4.0.2 version and xend started OK.

I agree that's safer.  In this case it was about a 4 hour yum upgrade,
so it wasn't really an option for me.

Yeah, I've been looking with interest at the memory ballooning
improvements going in, and wondering if the f15 branch will see a 3.1
(err, 2.6.41) kernel before it's all said and done.  Will we need a Xen
update for that as well, or is the current version feature-complete in
that area?
