The comment says it puts the card into the 'wait for key' state, which
is just what the code in isapnp_init() says its doing.
And isapnp_isa_attach_hook() calls isapnp_init()...
so it should be safe to put the cards into `wait for key' state
the same way that Linux does.

I'm guessing that the isapnp_isa_attach_hook is also re-enabling
response to the 3c509-specific ISA auto-scan.  I just dont know how
this might mess up a later isapnp probe, if it turns out hte board was
configured to pnp mode after all.

to put it another way: we need to test kernels configured for both isa
and isapno in two cases:

   1) card set up for isapnp by vendor firmware/bios
   2) card not set up for isapnp

What I suggested should (may?) fix #2, but may also break #1.

(Manuel: can you try a patch from where you are today?)
