I was about to point you to:
http://www.freebsd.org/projects/busdma/

But realized that you probably wanted status on 5.x, and not HEAD...

a quick look at the code shows that both em and bge are MPSAFE... I
can tell because of no references to Giant or GIANT, and that it using
XX_LOCK and has functions ending in _locked in them...

Maybe we need to expand the busdma project to include which driver
status for 5.x and HEAD?
