I wouldn't worry about this; I haven't been able to boot my MacBSD recently
without turning off 32-bit addressing.  I suspect it has something to do
with the Mac II defaulting to a 24-bit address space without the PMMU.

With regards to the 8M instead of 20M, do you see only 8M in your "About
this Mac" box with 32 bit addressing turned off?  In 24bit addressing mode,
you should be able to see only 12M total of RAM anyway.

I've been booting fine from System 7.5, too.

There seem to be an awful lot of Brads floating around in the
Mac-UNIX world...
