From what I understand of the Linux kernel, it uses two, and the i386 has
three modes of operation.
Don't forget that FreeBSD already runs on the VAX, and FreeVMS (in my
project concept) would be an extension and implementation of the existing
FreeBSD kernel so that it "looks and feels" like VMS.
I also wanted this implementation of FreeBSD to use native DEC filesystems
and operate classic DEC hardware.
