Erratum #93 is a "return from SMI" issue, and hence is no issue for
NetBSD.. but it may be an issue for a BIOS.

Most errata should be fixed in the BIOS. There's only one that
requires OS support that I can see right now (#100, I'll look
at that later).

Hm.. possibly.. what was your issue with the ioapic again? No
working interrupts?
