The PCMCIA subsystem is still responsible for detecting the card
insertion, identifying the type of the card, and if it's a CardBus
card, asking the PCI subsystem to enumerate the newly attached
device(s).

Once that's done, the hotplug subsystem will load the drivers for
those newly discovered devices.

This means that if you need to ensure that you have PCMCIA either
built in or loaded as a module, with yenta_socket, and ds.  You'll
also need cardmgr as well[1] so the situation is much like it was
in 2.4 times.


[1] actually, you strictly only need cardmgr if you're using PCMCIA
cards.  If you're only using Cardbus cards, cardmgr no longer plays
a role.  However, it's easier for the time being to just tell everyone
to run it irrespective. 8)
