My first guess was the "HSC-PCI" cards are the root of some new problem...

which are better known as "Card Mode Dino". But I don't think
that's the case since I never saw evidence of tulip getting loaded
nor any problem with configuring LAN.

Note that this LAN driver worked fine. Firmware programs
the MMIO address range for this card.
Any reason why tulip driver didn't get auto-loaded here?

Which I expect to be the LASI NIC.

Which suggests it's a problem with the Mux Driver somehow.
I expect a "login:" prompt to be the next output.

At one point there were issues with MUX driver keyboard input.
Maybe those issues have resurfaced in a new way now.

Start comparing the Gentoo Live CD kernel with the nearest revision
from debian or otherwise that fails.  MUX driver and serial support
in particular.
