Jeremy wrote up some new shinny code where the memory can be fragmented
(so that we can now stick in a big PCI hole). His patches are in
xen/balloon. But I haven't taken those and fiddled with them and changed
the toolstack (xm or xl) to actually take advantage of this.

Sheeshh. you are missing the mark. Instead of selling the lab equipment
you _send_ the equipment - that is like a X-mas present for geeks: shiny
new toy! :-)
But jokes aside, I haven't touched this since this last email. And I am
not going to get to it this week nor the next. Then there is one week
where (25th->29th) where I can play with this. After that, Linux Kernel
Summit and the Linux Plumbers Conference is in - so it will be quiet.
If this is a show-stopper right now, you could come with a hack where
the resource check is just ignored.
