(This is resent as my first email was HTML formatted and rejected by
the list. Edited and amended also.)

Cheers for trying them out! For the record, I think they were made
against 2.6.31, perhaps the original 2.6.31 rather than later 2.6.31.x
releases.

And also, I recommend using the mainline kernel for Ubuntu, especially
when trying these patches. It's available here:
http://kernel.ubuntu.com/~kernel-ppa/mainline/ - including source
packages.
