It was committed 3 years ago (kern_mib.c -r1.16). The commit log
doesn't say much, but there may have been a discussion on one
of the mailinglists.
I can only speculate ATM, but the only logical explanation I can
think of is that hw.machine would then mean processor type (class)
(ie i486, i586, ev4, ev5 etc), in the same way as CPU_TYPE.
