I have the older BNC/AUI model also. I haven't tried one recently, but
they should work under 1.2 and 1.2.1.

You need 32K of shared memory. That is all the driver supports. There is
some magic missing to support 16K shared mem. PIO mode (no shared memory)
is definitely not supported. (does the card really do that?)

This is odd, as the NICs are different.

Could be. First try it with 32K of shared memory, and one of the IRQ's
that is supported in if_ie.c. Let me know if you still have problems, and
I'll try to help get your card working.
