Simple reason, there are so many fundamental changes in/before 2.6.29
i.e. ext4 and in terms of video support (KMS, GEM) that anything before
2.6.29 (such as the 2.6.27 XCI tree) will be a waste of efforts if that
will be the next tree that should have long-term (until pvops merges
upstream, haha) support.

We don't need to wait for pv_ops to be merged. We just need it to have
near-enough feature parity. Actually now it supports HVM guests I'm tempted
to just move over to it.

Go ahead! It is really time to stop forward-porting stuff. The time is much better spent in adding the missing features to pv_ops/dom0. Also just after the 3.4 release is the perfect moment for that move, 3.5 should be able to ship with a pv_ops based kernel then.

cheers,
