[Warner Losh]

Author: imp
Date: Wed Dec 31 07:41:42 2008
New Revision: 186642
URL: http://svn.freebsd.org/changeset/base/186642

Log:
  When no driver attaches to a card, don't power down the card.  We can
  now read config registers of cardbus cards that are inserted, but
  aren't attached to a driver.
  Also, add a power related comment...
