Correct.

Agreed.

Moving forward I would think that you replace ISA bus attachments
with ACPI bus attachments until such time you don't have any ISA
drivers anymore. That is, you probably need drivers for ISA devices
that exist on alpha, so you'll end up with a handful of drivers
that have both ACPI and ISA. Hmmm, I don't know if this holds for
pc98 or not?
