I'm writing a device driver for a multipurpose I/O card (RTI815) and
I've been using inportb() and outportb() to write to the card (it's an
8-bit card).  So far it's worked fine, but having just read the FAQ, I
didn't see anything mentioned about these calls.  The FAQ instead
mentioned breaking the memory mapped address space of the card into
segmet+offset and calling a different routine (the name of which I do
not remember).  Why is my method working?  Should I use the alternate
routines mentioned in the FAQ?

Just for the record, I'm using V2 and Rhide (which are both
_excellent_).
