- 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.)
