Many thanks to all the folks who pointed this out.  I knew it, but didn't
think of it  - maybe if my IICX ran in 32-bit mode, I'd think of it
(hint-hint).  (BTW, notice Connectix ad for MODE32 in the new Macuser, 
in the section on Sys 7 compatibility?!)

And now for the second, tragic, part of the story.  I just called
my friend and said excitedly, proud of having an answer, "Turn 32-bit
addressing on and reboot!"  OK,  he did - and now the mouse cursor is 
frozen by the Apple menu!

Using keys, we can open the Memory CPanel, but can't get to that 
furshlugginer 24-bit radio button to turn 32-bit off, since the mouse
is frozen!  I had him try to reboot from a Sys 6 disk, but it opens 
up a dialog "You're in 32-bit mode.  Do you want 24-bit or restart?"
and neither button choice is defaulted (he tells me, at least) so he
can't reset it that way.  I tried zapping the PRAM (I had 
him hold down Shift-Control-Option - Command  (overkill, I know) -p -r 
keys -was this right?   I was/am panicked, by now!)
and no help that way.

I suppose it';s one of the INITs,, Radius or FastCache.  Anyone
have a suggestion for what I can do to help him turn off 32-bit
addressing long enough to, well, turn it off (in the Memory CPanel, 
that is)?

Thanks for listening.  How embaressed I am, what a comedy!
