The inb/outb functions have been replaced by the bus_space(9) functions.
As far as allocation goes, you should tell it in the probe/attach functions:

#define YOUR_NPORTS	8

	if (bus_space_map(iot, iobase, YOUR_NPORTS, 0, &ioh)) {

iobase you get from the driver definition line in your kernel config.
Look at drivers in /usr/src/sys/dev/isa for examples.
