[PATCH] Add locking to ahb(4)

[Warner Losh]

I have a full EISA system and a dozen of these cards, and other EISA cards, if anybody wants to take up tilting at that windmill.  I'm in Denver CO, and will drive it to your house, within reason.  The system is a dual CPU 533MHz Digital system with all the config disks, etc, you need to support changing EISA cards.  It ran FreeBSD 5.x and 6.x pretty well.

Sadly, my other commitments keep me from testing this myself...
