The PCMCIA utilities are supposed to have APM support to automatically
suspend/resume the cards when the system is suspended.  I'll check that
it is actually being compiled into the Debian packages before I make a
new release.

Unfortunately, some cards (most notably SCSI cards) can't do a
suspend/resume cycle, so eject/insert needs to be done.  But you are
correct, it is more appropriate for cards like network cards to do
a suspend/resume rather than an eject/insert.  That is why the apmd
scripts should be optional.
