PCMCIA lockups on 2.4.17-pre2-ben0

["Jeffrey W. Baker" <jwbaker@acm.org>]

Me again.  Powerbook G4 1st gen.  Cisco Aironet card in the PCMCIA
slot.  The powerbook is still locking up during wakeup under
2.4.17-pre2-ben0.  The lockup happens before the PCMCIA card is powered
up.  That is, when the machine hangs the card's LEDs are off.  Also, the
hang occurs before the X display is "fixed".  Those of you with this
hardware know what I mean.

I'm also getting lockups at shutdown time.  The lockup happens right
after PCMCIA modules get unloaded.  It feels like the problem is
definitely in the PCMCIA code.
