If the deviceID for any card using a 7870 is in our driver, it is
supported.

The 7870 is "a SCSI Controller on a chip".  It only needs external logic
to wire up a BIOS, differential drivers if you want diff scsi, and an
optional SEEPROM for configuration info.  It would be very hard to make
a controller with a 7870 on it that we didn't support.
