OK, got the box. I ran a 5.4-RELEASE, identical (as I just restored
dumps of my current workstation on it) as the one not giving problems on
Intel-based system. Regardless of the state of USB, I can observe the
mentioned issues (scattered sound, lagging mouse in X, etc while
untarring firefox's sources).

With USB, vmstat -i shows:

interrupt                          total       rate
irq1: atkbd0                         904          2

... and without it:

cvsup-ing current 6.0-CURRENT right now, to check the giantless VFS once
again. It will probably take an hour to get it up and running.

If you have any more ideas, while I still have the box, I'd be willing
to try, time permitting.
