Hi Linus,

We have isa_*() functions to access ISA memory space since a while.

I'm still missing isa_{request,release}_mem_region(), though.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
