One more question:

In the probe routines, the values of the hardware ports are changing from
one chipset to the next.  Throughout the ppc driver, the regular macros are
used to access the parallel port control registers, but in the probe routine
it reverts to inb/outb, probably because it makes no sense to allocate a
port for 2 or three operations, then deallocate it and choose another one.

So, should the inb/outb calls in the probe functions be left alone?  This is
specifically for the ppc driver, where several possible chipsets must be
addressed by one driver.
