I seem to remember you and I having a chat about this on the way back 
from dinner at USENIX, Jordan :-)

The "userconfig" stuff *would* be useful, I agree, but simply using 
FreeBSD's isn't going to work under NetBSD.  Our autoconfiguration scheme 
is fairly different ... especially the way locators are handled.  For us, 
it can't readily be handled by frobbing isa_device structures, mostly 
because we don't have them :-)

I guess, isa_scan() could ask, depending on RB_CONFIG or whatever, if the 
user wants to frob the locators for a given device before its match/probe 
routine is called...

Note that locator frobbing isn't applicable to every bus type.  PCI and 
EISA, for example, don't suffer from the same problem because they have 
discrete "slots" and device identifier tags...Thus, saying:

ncr*	at pci? dev ? function ?

...and...

ahb*	at eisa? slot ?

...covers all cases :-)
