No, it a diff of about 150 patches for natty from the base 2.6.38 kernel.
We upstream our patches.  Sometimes some patches will slip through for a
while, but they will go up.

Of the 150 or so patches not "upstream" there are only a few that are
ubuntu specific.  Some of the patches are backports from patches upstream
for 2.6.39, some are from linux-next or other development branches,
and some are from projects that aren't upstream for one reason or another
(eg. aufs).

Our delta is public, well documented and available to be examined any
time.  Just pull our kernels from

git://kernel.ubuntu.com/ubuntu/ubuntu-oneiric.git
git://kernel.ubuntu.com/ubuntu/ubuntu-natty.git
