Really?!
Hmm, how does the driver access ISA memory area? I did not find ioremap() nor
readb/writeb stuff. Usually those two macros are used to access PCI memory
space. That is the reason I said "the driver implies a PCI device".
If it is purely ISA driver, may it should use isa_read/isa_write macros, in
which case we can make use of isa_slot_offset (maybe isa_slot_offset is useful
after all. :-0)
