BTW, since creating a new backport involves copying a lot of files,
it's probably better for you to do it in git and we can pull it.

Yes, this makes sense. We probably want to test for something like 2.6.15-*-* to detect
ubuntu. But, no mixed-case please. And maybe we want to name it
2.6.15_ubuntu606 just so its clear which ubuntu version it is.

Micheal/Vlad,
This is not one of the kernels that has a set of backport files in
kernel_addons. So its pulling in the kernel.org 2.6.15 backport files.
Apparently Ubuntu has back-ported some stuff into their 2.6.15-23-server
kernel.
How shall we proceed? This isn't one of the ofed-1.2 supported distros
or kernels, yet you're building against it.
I'm willing to create a new directory
kernel_addons/backport/2.6.15_Ubuntu for this and do the backport if it
is the correct thing to do.
Steve.
