I don't get it either, but there's something else going on.

I have an Inspiron 8000 (almost 2 years old); I'm told Inspiron and Latitude
systems of the same vintage have the same motherboards.

I'm running kernel 2.4.20, without any ISA, EISA or Plug-and-Play support.

I have an old 3Com network card and an Orinoco Gold wireless card, and they
both work just fine.

So ISA support is not required for PCMCIA.

Attached is my current kernel config.
