This is not really weird, the IOC3 on the IP27 board has no NICs. We'd
have to trace the BRIDGE NICs or even HUB NICs to get the serials, so I
decided that it's an overkill. Although it will be required for reliably
detecting MENET (which has a serial# NIC on the BRIDGE).

This is weird. This means the keyboard will not be operational, and I wish
somebody (Ralf) looks into this. The IOC3 on IP27 BaseIO is a dual-slot
device (takes two IRQs, the INTA and INTA+2).

Serial ports will not use IRQs on IP27 unless somebody does dynirqs for
this arch. Nevertheless, if you pass 0 to register_serial() it will use
polling. Note that this is exactly the way IP27 always handled the serial
ports in ioc3-eth.c, so shed no tears :)

Good news this works. Anyone with Origin 2000 that had problems with MAC
NICs care to test?
