Did more testing (this time w/ pre7-8).

(I missed this in pre7-6, but at compile time, gcc complains that
 epic_init and epic_cleanup are defined but not used.)

With debug=7, I got this:

: epic_rx() status was 000019a1.

and continuing, sever entries per second.

Also, attempts to rmmod(8) the module produce an OOPS. Unfortunately,
although I had klogd -s running to catch it, it is not showing in the
logs. It is at least easily reproducable, if you have an epic card.
Happens every time w/o fail.

I'm now running pre7-8 w/ pre6's epic100.c. That does work.
