description:
Add a quirk for pgoyette@'s old (ACPI 1.0) NVIDIA board.

It was analyzed that this DSDT busy-loops some unknown PCI memory regions in
several places. Because the regions are apparently almost constant, this
causes several conditions where the interpreter might enter into an infinite
loop. Luckily ACPICA detects this and rightly spams AE_AML_INFINITE_LOOP
warnings.

Not much we can do. Declare as broken beyond repair. Set acpi_force_load=1
to use ACPI or use a custom DSDT.
