By the way, _does_ anyone have a contact at nVidia who could clarify?
Alan maybe? I'm quite curious what they did...

Summary:

Unless after booting with "acpi=off", outputs to port 0x80 (the legacy
way to delay I/O) reliably, but not immediately, hang MCP51 machines.
Outputs to port 0xed do not indicating it's a not a generic bus abort
problem.

Sorry, the first sentence didn't parse unambiguously for me.  Do you
mean "acpi=off" works, or that "acpi=off" allows *subsequent* boots to
work?

I have some people at nVidia I can probably ping.

Sorry, didn't see this again due to aforementioned horseshit ISP. "acpi=off" works it seems. Report from David Reed here:

Have them search on Google for:

  hp tx1000 noapic

:)
