Dieter,
I didn't know that of Apple. That's very interesting. I know there are 
already for over a year talks about completely different kind of 
bootstrap loader+ advanced programming tools such as EFI you mentioned 
but until now no motherboards has appeared for Intel/AMD processors with 
it.
Your solution of booting from an USB stick is what I intend to do with 
my firewall: a stand-alone memory-only system (I'm a little paranoid 
with respect to security) running LEAF (the Bering-uclib variant) but 
it's an idea for workstations as well as USB sticks become very cheap.
