Powering down / 'stop'ing cards under NEWCARD?

[cbiffle at safety.net (Cliff L. Biffle)]

One thing I noticed when I upgraded to -current was that pccardc no longer 
worked.  There were no device nodes for my PCMCIA controllers, etc.

This hasn't bothered me until now, as I've found a card (3Com EtherlinkIII) 
that seems to want to be properly shut down before eject.  Otherwise, it 
hangs the machine hard.

That specific problem I'll deal with another day, but for now, is there any 
way to 'stop' a card under -current with NEWCARD?
