Oh, and to test it, simply start it up with elevated privs on a box with a
firewire controller. It should report number of controllers found, current bus
generation, etc. You can try issuing the command 'br short' to see if it
properly issues a bus reset to the controller or 'r . 0 0xfffff0000400 4' to
read the first quadlet of the card's config rom, which is some header CRC and
length info, or offset 404, which is the 1394 header. For example:
...
Command: r . 0 0xfffff0000400 4
reading from node 0, bus 1023, offset 0XFFFFF0000400 4 bytes
read succeeded. Data follows (hex):
04 04 22 8E
Ack code: complete
Command: r . 0 0xfffff0000404 4
reading from node 0, bus 1023, offset 0XFFFFF0000404 4 bytes
read succeeded. Data follows (hex):
31 33 39 34
Ack code: complete

It gets far more interesting with devices connected, of course.
