If the error messages in the BGRT driver make it impossible for end
users to achieve a pretty boot experience then I agree, that is a
kernel bug. BGRT is an exception to the usual rule about complaining
loudly when we encounter firmware bugs simply because we're dealing
with UIs in this case.

That's not to say we should give up reporting these kinds of invalid
table issues to firmware developers altogether. There are other means
of doing it, and comprising the wants of many end users for the
benefit of few firmware developers (relatively) is just not sensible.

Colin, Ricardo, I haven't checked recently, are there ACPI BGRT
validations tests in FWTS and LUV? Josh (Triplett), BITS would seem
like a very good place to include these tests since it already has a
bunch of ACPI table checks.
