work linuxbios with openbios

[Greg Watson]

This is a work-in-progress, so there is no documentation. The major 
issue that needs to be addressed is that there is currently no 
mechanism for passing the linuxbios discovered device information to 
openbios. This is on my todo list.

Openbios is an implementation of the IEEE-1275 standard for Open 
Firmware. This provides a standard means for loading an operating 
system image from a device, as well as a series of callbacks that an 
operating system can use to perform certain functions, such as writing 
to an attached display. It is similar to filo in some respects, such as 
the ability to load images from attached devices, but provides an 
architecture neutral layer that simplifies the interface between the 
operating system and the hardware. This means an Open Firmware enabled 
kernel will run on virtually any platform that provides Open Firmware 
support, without requiring kernel code that is specific to the 
platform.
