The first PCI machines were 486 based. The early 486 machines used EISA bus,
VL in addition to ISA, or maybe plain ISA. The 486 came out before the PCI
bus. When the 486 hit it's peak (486-100 class machines) the PCI bus was
just beginning.
I have not seen or heard of a 386-PCI system, although they may be used for
some special applications (not commodity PCs).
A 386 with an ISA bus could not get full bandwidth out of 10baseT. I don't
recall seeing anything better than about 600KB/s, although with a recent
kernel I'm sure you could get better than that I doubt it would be a full
10megabit.

It does sound like it would be a good idea to have a separate build for 386
and 486, then we could optimise everything else for 586+. We can even use P2
machines for build daemons so we wouldn't have the speed problems we have
with M68K... :-#
