Thanks for the reply.  A few notes / questions below.

> (2) You might find that the BigMac interface is defaulting to half-duplex operation, which modern switches/hubs tend not to like at 100MBit/sec. I'm not sure if BigMac even supports full-duplex at 100Mbit/sec, but if it does, you may need to force it using OpenBOOT commands.

It is.  It seems to work (my switches are fine with it).  Obviously not optimal though...

It might be worth inspecting the NetBSD system "messages" file, for any warnings about "late collisions" or "invalid packet sequence" or something vaguely familiar - one of the signs that there is a duplexing disagreement between the "be" interface and the switch it is connected-to.
