The APM stuff I have browsed through for Linux does exactly this
-- each PCMCIA driver registers (or should register) "before" and
"after" hooks with the APM part of the kernel.  I have also
browsed through one of (?) the PCMCIA variant(s) for Linux which
seems to have a sort-of sensible framework (which needs some
major work for NetBSD, btw.).  The good part about that PCMCIA
code is it's not copylefted.  Any takers?

A good start for browsing through what I've browsed through would
probably be
