The compact PCI hot swap spec isn't implemented in FreeBSD at this
time. The compact PCI cards will work w/o the hot swap stuff just
fine. The hot swap spec doesn't include a register set to program to,
as far as I could tell in my limited researches, so each chipset needs
its own driver to add hot swap capibilities.
