I gave it a shot anyway.  Converting to PATA was surprisingly straighforward.

Anyway, I now get the following when running SMART long tests on /dev/sda:

  ata1: lost interrupt (Status 0x50)

And the machine hangs...  So I'm back to square one.
How do I prevent lockups on the system when running SMART long tests?
