That appears to have been the case. He sent me a glossy (glossy MAROON!)
blurb that indeed said OS/2 did not use 32 bit mode.

Genius, well I wouldn't know. But Unix and OS/2 are not similar things.
Unix is a MULTIUSER operating system. OS/2 is single user. Unix
is missing several things that OS/2 has: in particular,
device monitors, installable device drivers, and the ability to
do IO (but unfortunately not to capture interrupts) in user mode.
The main thing Unix has is portability. But in the IBMPC world,
nobody cares a hoot about portability. Of course, all those things
could be added to Unix. To me the ability to do actual IO in user mode
is absolutely vital.
