ACPI is an interesting conglomeration of standards, and it
comes in a couple of pieces.

- A table of that points to various configuration tables in
  the system.  
- A device tree represented as a pile of AML code, for
  the kernel to interpret.

The idea with ACPI is that the policy and the control should go in
the kernel, and in the device drivers.

With LinuxBIOS and everything being open source writing AML code,
instead of just writing/updating the appropriate driver seems silly.

The table of pointers to well know configuration is a good idea,
that I will probably explore.  LinuxBIOS has pushed just about
as far as it can go without incorporating explicit support in the
kernel for it.

Device trees can be represented with a pure table instead of needing
code to implement them.  And without code they should be much more
reliable so that is the route LinuxBIOS is likely to take.

All of this is just the LinuxBIOS native interface.  If someone wants
to load code to have LinuxBIOS look like a more traditional BIOS they
can but we haven't started concentrating in that area yet.
