Jeff,
At the Advanced Computing Lab of Los Alamos National Lab, we added some code to jump to the kernel, display error messages, and set up the interrupts. We modified OpenBIOS 0.0.1, so 0.0.2 may have already done some of that.
Our goal is to get a linux kernel and a shell onto our Intel L440GX+ BIOS so we can network boot, etc. We also have code to boot Linux from Linux, so we won't use the bootstrap kernel as the final kernel.
This probably won't help you, but it may. We'll publish our code as soon as it is a little more finalized. If you want I can send you what we have so far.
