gawd no!  you would even suggest such a thing in public?  sheesh! :-)

this is a thinkpad t40p.  4.9-release cdrom boots through to em0
media just fine, and i just retested that assertion without moving
any wires etc.

i tried booting wigh acpi off.  no change.

it stalls scanning for dhcp servers, which do exist, and then puts
up the NetworkConfiguration menu.  if i say no to dhcp and hand
configure, no packets leave the interface.
