It seems this is related to your patch 6 changes or what I said should
be split. There's something funky there and I think everything should be
kept "closer" if not merged together.  It could get ugly, but getting it
all done and explained at once would be best IMO.

It seems what you're indicating is that the two shouldn't have been
combined into one CAP.  Still that seems to be counter intuitive to the
first part of this series which was merging caps.  It's a bit confusing
to say the least ;-)!

Also you'll have a merge to handle with this patch...

/* -device virtio-vga */

Before an ACK - I'll be interested to understand the relationship w/
patch 6 and a bit of the history/reasoning for a separate cap
(especially in light of combining other caps).
