Do you really?  I mean, yes, theoretically, I understand it, the
hardware supports 64kB of I/O port space per root port.  But I/O
port space is rather deprecated these days.  My laptop has precisely
two devices with I/O ports, one with 64 bytes and the other with 32
bytes.  Would you really suffer by allocating 16kB of I/O port
space to each root port?
