i386 support was removed by purposes because this CPU lacks support
for atomic operations. Adding it back would be difficult and probably
cause a performance loss for all other systems. Ther are also
fundamental problem with NFS because the i386 CPU doesn't allow
write protecting pages in the kernel.

I am surprised that companies still built x86 CPU that aren't at least
i486 compatible.

        Kind regards
