Yup.  Dead as a dead horse.  The other card is very alive.
This problem does not exist under 3.0-current 9as of today).

BTW, under SMP, this driver panics.  This happens under NFS load.
What one sees is:

Page fault on cpuid = 0;

It blows on fxp_add_rfabuf + 0xc7.

We get there via:

fxp_add_rfabuf
fxp_intr
smp_idleloop
fork_trampoline  (wish had a clue what a trampoline is  - other than the
Kmart
                  type :-)
