 This was caused by a change in default hints.  To get the old behavior,
 you can add this line back to /boot/device.hints:
 
 hint.atkbd.0.flags="0x1"
 
 Alternativly, you can apply this diff to your devd.conf.  That won't let
 you work in single-user mode since devd doesn't run there, but it sucks
 less then the default.  What we really need is an in-kernel keyboard
 mux.
