I don't have my kernel tree with me (I'm at vacation atm.). The patch
is made with only the -uN options, but I can make a new one on Friday
(if needed).

Thanks for the help!

The patch doesn't apply to current kernels and fixing it looks non-trivial.

There's no hurry - please email us a complete (tested, changelogged,
signed-off) patch when you have time to get onto it, thanks.
