it's easy:

First load a good kernel
(so you can boot into your system)

then git clone linus's tree.
make compile install, reboot

if you hit your problem
then reboot with the good kernel.
change to the source tree of linus's git
(that's giving you this issue)
then do:
git bisect start
then tell git bisect the bad kernel to the good
i.g.
git bisect bad (either leave blank for present or do v2.6.*)
then
git bisect good v2.6.31-rc* (to the last good kernel).

then git bisect will start with it's first commit
(now make the kernel, no need to look for a patch,
as git has already done this  for you).

then reboot with the kernel(linus's git) that your bisecting
if you hit the problem, then reboot into the good kernel
change into linus's tree and do:
git bisect bad

then git bisect will give you another commit to try.
make the kernel reboot and see if you bootup.
when you finally boot up without issues
do git bisect good save the results and
post it to lkml.

see not so bad(just use a small .config or else
you spend a lifetime compiling)
