Hey Ira,

I've been slowly hacking on your virtio-over-pci stuff.  I've got an
initial series of cleanup patches which address some of the comments
from this thread.  Before I send them to you, have you made any
changes on your end?  They likely won't apply without changes to the
core code, so I'd like to sync up with you first.

Cheers,
g.
