Note, that AIX maps these differently.  Attached is the relevant information
from lsresource -a -l bus0 on AIX from this machine:

I    scsi0  bus_intr_lvl                   7    (B0)   
I    ent0   busintr                        6    (B0)   
N    sa0    bus_intr_lvl                   4    (A0)   
N    sa1    bus_intr_lvl                   3    (A0)   
N    sioka0 bus_intr_lvl                   1    (A0)   
N    sioma0 bus_intr_lvl                  12    (A0)   
N    fda0   bus_intr_lvl                   6    (A0)   
N    siota0 bus_intr_lvl                  15    (A0)   
N    paud0  bus_intr_level                 5    (A0)

Note that the device ppa0       Available 01-B0        Standard I/O Parallel
Port Adapter does not have an interrupt.  AIX probably doesn't use interrupt
driven paralell ports.


sio* are keyboard bits
paud is audio
sa* is serial
