Here's my reasoning: this is a CheckPoint product, and it looks like an
appliance, not really a general-purpose machine.  The issue has apparently been
there from day one, and the kernel shipped on the machine complains noisily
about the issue, but apparently nobody bothered to investigate it.

This corruption will clearly break other ACPI-related things.  We can sort of
work around this one (though the workaround does prevent us from doing any PCI
resource reassignment), but we have no idea what the other lurking ACPI issues
are (and we have no assurance that *only* ACPI things are broken -- maybe the
memory corruption affects other unknown things).  It may take significant
debugging effort to identify the next problem.

The only report I've seen (this one) is apparently from a CheckPoint employee,
so it's not clear that anybody else is trying to run upstream Linux on it. 
Being a CheckPoint employee, J Bauer is probably in a position to get the BIOS
fixed.

You might still be able to convince me, but it seems like the benefit to a
quirk for this platform is small, and it does cost everybody else something in
code size and complexity.
