I'd opt for an approach based on the available 2.6.29 tree from Andrew 
but delayed until 2.6.30 is out.
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.
On the other hand it might make sense to use the same kernel version 
that RHEL6 will be using to take advantage of their (driver-) 
backporting efforts (not sure how heavily that has been utilized in 
2.6.18). Any insider infos from the RH guys here on the list what kernel 
that might be? ;-)


As a side-note, there is known issue with Andrew's tree not compiling on 
x86_32 with a recent gcc. If I remember correctly that was due to 
optimizations, further details here:
