I've hopefully fixed this mistake now..  The problem was a side effect of
the card being given a memory address and the driver turning it off because
there isn't memory (ie: an ne2000).  Removing the specification entirely
would fix it, or updating to the latest isa_compat.c should also fix it.

Why now?  If you'd been reading the commit messages, you'd know the
configuration system has had major changes committed...
