I'm not using the loader. I netboot the kernel with hints compiled in.
The board has no VGA device, so I use a serial console, but the bios
doesn't support a serial console. All I can do is wait for the bios
to get etherboot loaded and then I get my serial output.

As far as ACPI is concerned, I haven't got that built into the kernel and
there are no modules for the kernel to load and no loader to load them.

This is a very simple kernel:
