Most of the bootstrap code I've seen just locates the remaining OS Loader and proceeds. I'm certain that the more modern systems look for ACPI or PnP BIOS info, and at least note its location and existence, before they resume the rest of the loading.
Of course, it's also posible I've overlooked something. It's not like I've looked at EVERY project on the site, much less every bootloader in existence...
At one time I had some code I ran on one of my older boxes to see if it had a PnP BIOS- it did (had the register settings mentioned in the spec). Might see if I can dig that up, if it'd be of any help.
