Initial check-in for support of 32-bit CardBus PC Cards; from NetBSD. On many

machines, this code needs the new PCIBIOS* options enabled in the kernel config
file to work, but your mileage may vary. Included is a working 3c575 driver for
3Com 10/100 CardBus PC Card NICs (tested only with the 'C' revision). The 3c575
is the pccard version of the PCI EtherLink XL cards, and thus the xl driver has
been split into /sys/dev/ic.
