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)
