I am not ignoring the message, I simply wasn't sure how to interpret it
properly :) This cable and controller somebody gave me could have been faulty
perhaps. Thanks for confirming that they're apparently functioning fine.

That makes sense, as irq 4 is now also used for the B channel. I vainly tried
to disable COM1 in the BIOS but that didn't seem to help either. Nor did
disabling the sio device. So I'll send a message to -current now.
Thanks for your help Justin.
