Does anybody know whether /dev/mem and/or /dev/kmem exist in MINIX ?

I seem to recall a discussion in the then net.unix-wizards about
a year ago on running UNIX on an ibm pc. The consensus seemed to be
that multi tasking was hard because there is no memory protection
hardware. A process could presumably overwrite the kernel. How did
Andy solve this problem ? Is a MMU a standard part of a pc ? These
questions may be naive but I know very little about the pc hardware.
