	I have seen this error on my SE/30 with the mrg kernel.  In my
case, it appears to have been caused by a failure to set 32-bit
addressing in the Memory control panel.  I was under the mistaken
impression that turning on Mode-32 gave 32 bit addressing.  I was also
unable to boot multi-user, and single-user mode crashed after
executing a few commands.
	Setting 32-bit addressing cured my problem; I no longer get
the "too many NuBus ranges" error, can boot multiuser, and am able to
use dt, X11R6, emacs, and tcsh.  I am still having some so far vague
problems with the compiler tools, in particular in attempts to compile
	I am fairly certain that 32-bit addressing was not required to
boot the alpha and beta versions; at least, I don't remember enabling
32-bit addressing for them.  However, my installations of those
systems were never very stable.
