NetBSD provides machine-independent bus support and
  drivers for CardBus devices.
The cbb device represents the CardBus
    controller. Each controller has a number of slots, represented by the
    cardslot devices. A slot can have either a CardBus
    card or a PCMCIA card, which are attached with the
    cardbus or pcmcia devices,
    respectively.
NetBSD includes the following machine-independent
  CardBus drivers, sorted by function and driver name:

cbb devices may not be properly handled by the system
  BIOS on i386-family systems. If, on an i386-family system, the
  cbb driver reports
cbb0: NOT USED because of
  unconfigured interrupt
then enabling
  - options PCI_ADDR_FIXUP
- options PCI_BUS_FIXUP
- options PCI_INTR_FIXUP
or (if ACPI is in use)
  - options PCI_INTR_FIXUP_DISABLED
in the kernel configuration might be of use.

Thecardbus driver appeared in NetBSD
  1.5.
NetBSD maps memory on Cardbus (and therefore PCMCIA
  cards behind Cardbus) in order to access the cards (including reading CIS
  tuples on PCMCIA cards) and access the devices using the RBUS abstraction.
  When the mapping does not work, PCMCIA cards are typically ignored on insert,
  and Cardbus cards are recognized but nonfunctional. On i386, the kernel has a
  heuristic to choose a memory address for mapping, defaulting to 1 GB, but
  choosing 0.5 GB on machines with less than 192 MB RAM and 2 GB on machines
  with more than 1 GB of RAM. The intent is to use an address that is larger
  than available RAM, but low enough to work; some systems seem to have trouble
  with addresses requiring more than 20 address lines. On i386, the following
  kernel configuration line disables the heuristics and forces Cardbus memory
  space to be mapped at 512M; this value makes Cardbus support (including PCMCIA
  attachment under a cbb) work on some notebook models, including the IBM
  Thinkpad 600E (2645-4AU) and the Compaq ARMADA M700:
options
    RBUS_MIN_START="0x20000000"
By default, on i386 and amd64, the kernel uses
  RBUS_IO_BASE as 0x4000 and
  RBUS_IO_SIZE as 0x2000. On some machines, this fails,
  due to a requirement that these addresses fit within 12 bits. The following
  kernel options have been reported as helpful:
options RBUS_IO_BASE="0xa00"
options
  RBUS_IO_SIZE="0x00ff"
