Have a look in /sys/i386/conf/LINT.

I guess it's a bit dodgy to try writing to the memory and reading back.
You may hit some memory-mapped hardware.

Although Novell (3.11 anyway) isn't. OSs like Win95 and OS/2 have a
user base that doesn't know the difference between disk space and
memory (I'm not saying all of their user base is such). If they offered
the user the ability to specify the amount of memory, they'd be shooting
themselves in the foot ("Hmm, how much memory.... the leaflet says 1.6Gb!").
They *have* to figure it out for themselves and assume that they know
about *all* hardware on the machine.
