Maybe now is a good time to do so :) Ben Gray's PMAP stuff looked like a bodge to me (and I know nothing about PMAP!). I have his stuff dropped onto CURRENT at the nearest-guess-equivalent to 8.0-RELEASE which is what he used. This is the SVN tree before I took an axe to it. I've put it in http://people.freebsd.org/~markm/arm.tar.gz, and its a drop-in replacement for src/sys/arm, with the SVN metadata.
