	I'm not sure that answer of my third question could be found in schizo 
manual :-P

	If I have understood, autoconfiguration enumerates physical device and 
tries to configure these devices. I have noted that schizo0 is connected 
to PCI-B (and not -A), but I have no idea to check that schizo0 controls 
cpu0...

	You're welcome. This evening, I will try to pick up my Blade 100 (that 
is currently stored in my garage) to propose an UltraSPARC-IIe driver.
