Define the 3Com "RoadRunner" chipset; like the Boomerang, but for PCMCIA.

No DMA is wired up, it has a shared memory interface, and a FIFO buffer
which can be used to speed up PIO transfers.  (The latter two are
PCMCIA-specific speed hacks to deal hide the performance lossage from
using a PCMCIA->PCI bridge internally.)
