Okay, I'll take a look at what changes there have been to IO-APIC and
ACPI code up to Linux 2.4.25 -- certainly the most recent 2.4 kernel
matches your IO-APIC version and doesn't print the 'unexpected
IO-APIC' message.

Perhaps there is some 'quirk' fix that we are missing -- VIA boards
usually need a few of those (the general opinion of VIA boards among
Linux kernel developers is pretty low, I think :-).
