If the PCMCIA/Cardbus in-kernel support is the same as 2.4, PCMCIA cards
get handled by the original cardmgr/cardctl userspace apps, but Cardbus
(due to it's PCI-like nature) gets handled by the Hotplug subsystem, so
it's two separate things really.

You might just need to rebuild the pcmcia-cs package so it knows to use
the in-kernel PCMCIA support if it was originally using its own bunch of
kernel modules for support.
