  | aha. Im using a AUI->BNC transceiver.

That's fine.  Your error has nothing at all to do with the transceiver.
An overflow error from a lance indicates that the lance couldn't get
enough memory cycles (via DMA) to store the packet in memory as fast as
it is arriving off the wire (which is at a fixed 10Mbit/sec).

There is probably not a lot that you can do about this, aside from deleting
the message from the kernel so you aren't bothered by it all the time.
The lance driver is just a little noisy about some errors (though really,
on properly designed hardware, which Suns usually are (or were) this particular
error should never happen).

Do you happen to have a lot of other DMA activity competing for bandwidth?
