On my VS3100 (KA-42A cpu, 24mb RAM), building the NetBSD kernel
takes ~5 hours.  "Days" is surely exaggerated for anything but perhaps
a VS2000 w/ 8mb or less and polled-io SCSI.  There are several factors
that have to come into account for such a worst-case situation :).
Anyways, building the entire NetBSD (i.e. userland) would take
approximately 1-2 weeks on my VS3100, I haven't been able to test
it yet, because 1.4M and a later snapshot builds failed to run through
but I hope to get it done when 1.5 comes near.  I certainly want to
build world on such a, well, slow and old machine, since it's so
fast and boring on the modern off-the-shelf x86 PCs.
