Well, I meant GIVE it USB using a PCMCIA card... Then add 1+ serial

Not really. You need a serial port. You think you have one with the
console but it will hurt when the thing is emitting errors.
We've done this ride, it's in the archives.
Someone hacked openbsd (see the archives for this list about serial
ports) so the boot code could redirect the console to /dev/null.
Perhaps linux offers something similar.
While you can ssh to it, and debugging isn't an issue, you get
no room for whining when it doesn't respond and you can't tell why.
I'm sorry the second serial port got buried under a PCMCIA slot.
I dunno if it's available somewhere else on the board (snagging
some pins from some chip somewhere...)
I'm happy COM2 is a header on the 4801.
