help? need to enable VT-d for 2.6.27

I'm in a bit of an odd situation. We run an embedded version of linux
on many different boards with different vendor agreements so it's
painful to upgrade kernel versions.

I've been asked to provide VT-d support for KVM on our kernel (primarily
for mapping NIC VFs into the guests), and I'm trying to figure out my
best option to get a working implementation.

Looking at the kvm git tree, kvm-77 seems to be based off 2.6.27.
Should I look at porting that?

Would I be better off just scanning for anything VT-d related in 2.6.28
and backporting it?

Are there any better options? Any advice you could provide would be
appreciated.

Thanks,
Chris
