I don't believe recent FreeBSD kernels don't support 386 anymore by
default, and IIRC, noone is really sure if it actually works. Also, the
linuxthreads port in glibc wanted i486.
I see no real reason to use 386 anymore, they're unusably slow, and if
someone really needs it, there's always pbuilder.
