There are parts that could be, but the ISA enumerator and root PCI bus
discovery code pose some awkward problems; if the ISA enumerator wasn't
present at boot time, the PnP BIOS enumerator will have run instead, and
you don't want to duplicate everything (which will happen when the nexus
is reprobed after the module load). And you don't want to re-discover the
root PCI bus(ses) after the ACPI module load either. 8)
You also don't want to load ACPI if you have APM running, since they
don't really coexist very nicely.
