	I'm getting 16 minutes with GENERIC kernel + added things and
disabled WITNESS options on a P4-2.6Ghz Mobile CPU 2GB DDR266 memory.

I'm using:
time make buildkernel KERNCONF={NAMEOFKERNELECONFIGFILE}

	But I think we're talking about buildworld times which has
something to do with the kernel that is already running when you do the
buildworld.  My buildworld was 150 minutes with WITNESS and 74 minutes
without WITNESS.
