Right now the pccard suspend methods detach the cards. In general, it
isn't possible to know if the card is replaced while the system is
suspended, and there are some reinitialization issues that doing this
"fixes". If you remove the detach from the suspend path, that's a
first set. The next step may be to hack whatever driver(s) you are
interested in to properly reinitialize. There may be some power
issues as well. src/sys/dev/pccard is a good place to start looking.
