In general, ACPI code can work with memory or device registers that have
been initialized by the BIOS and depend on them. It's possible to write
ACPI code that depends on preceding BIOS code. I don't know if that's
the case with our ACPI implementation.

I have a truly marvellous patch that fixes the bug which this
