I returned the borrowed Sil card and plugged my new Via card back in again and now see no problems even with the old kernel. That's with no PATA disk in the system any longer, So it looks like having a PATA drive plugged in to the motherboard is a precondition for the bus errors on the adapter cards. Too many variables, my head hurts. But at least it seems there are no outstanding problems from this scenario going forward.
