I wish kithrup still had it's xenix kernel, so you could see the difference.
What was it, you ask?  Well, kithrup's xenix kernel was about 500k total,
and that included STREAMS and whatnot (my ex-housemate ran X on it, so we
bumped up some limits, and put in a few extra device drivers).  kithrup is
running with networking, STREAMS, and whatnot.  (No NFS, though.)

I have seen SCO UNIX kernels approaching 4Mbytes (lots and lots and lots of
drivers, mostly); I have also seen xenix kernels approaching 2Mbytes.  The
main difference, at that point, is that there *is* so much more for unix:
filesystems (cd-rom, dos, nfs, rfs), more device drivers out there, etc.
