Hi Wing,

   Great work!  It would be really good if we could get this into
upstream for 3.2.  It will of course need to get submitted via xen-devel
for that to happen.  We've past 3.2 feature freeze, but I hope that
since this is completely self contained and fits into the existing
device structure, that it will be considered.

   What's the lineage of this driver?  It looks quite a bit different
than the code in Qemu CVS.  Is it a fork of the driver there?  Is there
another external source control with newer revisions?  It might help
getting it into upstream if we know where it comes from and why it's
different than Qemu.  Thanks!
