The average firmware implementation contains alot of dark magic about
hardware initialization.  Producing a decent replacement is not trivial.

The current situation is that every vendor has a favorite firmware
implementation or sometimes even several depending on vintage or endianess.
Repeated problems over the years have taught me the only productive
way to live with most firmware implementations is to touch them as little
as possible since the rules for coexistence with the OS are usually very
weakly worded, inconsistent across platforms and the governing features
generally are bugs, incompatibilites and lack of features.  End of rant :-)

How x86 or Linux centric is LinuxBIOS?  Makers of Linux devices want to
support other operating systems as well.
