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.
It's also possible to write C code that makes extensive use of goto. :)
To be fair, ACPI bytecode for actual hardware may need to rely on the firmware because of limitations in the hardware. But I think qemu is one instance where any ACPI bytecode can be kept simple.
I don't know if that's the case with our ACPI implementation.
Where is that code? Who has the ASL for qemu? Who wrote it? Is it big?
