Not without some modifications. They currently provide patches for
vanilla 2.6.36, 3.0.9 and 3.0.43

Yes. So I don't always upgrade whenever my distro does. I keep an eye
on the commit log to see if there is anything specific that I
must/want to upgrade for.

I don't know, no. I wish they would. It would make my life much easier :)

FWIW, I wrote up a bunch of stuff I did to make my laptop more secure,
including using TRESOR, last year. There are some useful links in it:
