First, please don't top post.  Looking at this message you can see why it
really doesn't make sense. :-)

Now, in short, to run a git bisection:

(1) clone the Linus' tree (see http://linux.yyz.us/git-howto.html#download_first_time)
(2) from within the kernel source code directory downloaded in (1) run
	$ git bisect start
	$ git bisect bad
    (this will mark the last revision as a failing one)
(3) If you have already verified that 2.6.24 works correctly, run
	$ git bisect good v2.6.24
    (this will mark the 2.6.24 kernel as a good one)
(4) as a result of this, git will select a kernel revision between 2.6.24 and
    the most recent one for testing.  Compile it, install it and check if it
    works.  If it does, run
	$ git bisect good
    Otherwise, run
	$ git bisect bad
(5) repeat (4) until there's no more revisions to test.

If you encounter any problems, please ask what to do next.

Thanks,
Rafael
