Maybe I'm missing something.

Why do you have to have a seperate probe?

Why can't you use the same probe routine address in two "driver instances"?

And wouldn't this fix the interrrupt attach problem introduced by the
eisaconf code in the VLB Adaptec case?

You keep saying you need to duplicate cade -- I don't see it.  I see
that there is a need to duplicate ~32 bytes of data structure to get
an EISA and non-EISA device instance.  Tell me why Im wrong...
