My main concern is the device model code and that code is either from 
QEMU, Bochs, of VGABIOS.  The stuff written from scratch (SATA and OHCI 
support) is not available publicly.

There's a lot of divergence and a lot of code restructuring (especially 
in the VGA code) that makes merging cherry picking stuff extremely 
difficult.  Most of the changes make no attempt to maintain consistency 
with the rest of QEMU.

If ya'll are interested in merging stuff back upstream, then I'm happy 
to work with you on it.  It seems like a huge task though and, as I've 
said, I've seen no effort or interest from Sun on this.  It's really 
unfortunate because there have been many bugs found in Xen, KVM, or QEMU 
that I've gone back and seen fixes for already in VirtualBox.  Likewise, 
there are fixes in QEMU/Xen/KVM that are not in VirtualBox.  It's a huge 
amount of wasted effort.
