that's good work.  i put out a 9load-e820 with a revised rtl8169
driver that should complain if the mac is not recognized but the
vid/did are rather than putting the 8169 into this state.

if this works, i'll put similar changes into a 8169 kernel driver.

i believe several other people have seen this problem with
similar hardware.
