Yes, you noted correctly that the stx104_base module parameter fulfills
the same function as the io module parameter used in many of the radio
drivers: it's an array holding the io port address of each device.
However, I find "io" to be a rather vague module parameter name, so I've
decided to use the more apt "stx104_base" name for my array of base
addresses.

As you've probably noticed, there are few ISA drivers existing in the
kernel baseline currently, so not much of a standard is set yet. I'm all
right with renaming the module parameter if you have a preference, just
as long as the name is more informative than simply "io."

For what it's worth, this driver is part of a series of PC/104 drivers
I've been submitting to various subsystems (in the hopes of improving
the lack of PC/104 support in the baseline Linux kernel); see
drivers/gpio/gpio-104-idio-16.c and drivers/gpio/gpio-104-idi-48.c for
example. I have thus far been following the convention of naming the
base address module parameter as "modname_base," where "modname" is the
respective module name.
