My bad.  I forgot I hadn't given the git bisect demo.

So, it works like this:

	git bisect start; # we're bisecting!
	git bisect bad v3.2.4
	git bisect bad 76531d4166; # tested bad
	... continue listing bad commits ...
	git bisect good 7d339ae99

Now git will choose a version to test.  So:

	make silentoldconfig; # reuse configuration
	make -j4 deb-pkg

That produces a package to try.  Once you see how it behaves, you can do:

	git bisect good; # if it shows one HDMI output
	git bisect bad; # if it shows three
	git bisect skip; # if some other bug makes it hard to test

And then git will check out another commit for you.

If you have the gitk package installed, you can run "git bisect visualize"
at any step to watch the regression range narrowing.  Eventually it will
find the first bad commit, but if you're bored before then, you can run
"git bisect log" to get a log others can use to pick up where you left off.

Thanks and hope that helps,
Jonathan
