Subject: - Functional changes to PCCARD support.  * Kill individual drivers
 'suspend' routines, since there's no simple/safe    way to suspend/resume a
 card w/out going through the complete probe    at initialization time.  *
 Default to using the apm_pccard_resume sysctl code, which basically   
 pretends the card was removed, and then re-inserted.  Suspend/resume    is
 now 'emulated' with a fake insert/removal.  (Hence we no longer    need the
 driver-specific suspend routines.)
