> [4294678.019000] IOC3 part: , serial:  => class IP27 BaseIO
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?
