I tried both cam and bio -- no difference. It is not that it's
slow -- I was prepared for that, it is that it totally hangs --
forever.

I narrowed it down to softupdates. If I disable the softupdates on
the cartridge's filesystem copying finishes successfully. Somehow
the `cp' process takes 150% of the CPU time (purely single CPU system),
but that's a different story, I guess.

I hope, this sad experience of mine will help further improve
softupdates.

try searching the lists, my suggestion is to compile like so:

controller  ppc0  at isa? disable port ? tty irq 7

change to:

controller  ppc0  at isa? disable port ? cam irq 7

-----------------------------------------^^^

you may also want to try 'bio' it's been explained on the lists and i'm
unsure.
