I'm in a bit of an odd situation. We run an embedded version of linux

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.
I've had pains with VF passthrough with as late as a Fedora 14 kernel
(2.6.35). Ended up punting and moving to 2.6.39.
Ouch. Not good news, but not entirely unexpected. Are you doing
anything complicated, or was this just basic functionality that wasn't
working?
Looking at the kvm git tree, kvm-77 seems to be based off 2.6.27. Should
I look at porting that?
By 2.6.27 do you mean WRL3 or something else?
Yes, that's correct. (Wind River Linux 3, for the non-embedded types
out there.)
