If you're Joe Average user, you can't use inb, outb and friends. Try
running your program as root, and use i386_iopl() to enable access
to I/O ports.

Does your program really need to access I/O ports? Is there no way
to stick the functionality that needs this access in a device driver,
as is usually done?
