That's the ae driver, then.  So we just need to find the RAM, PROM, and
register addresses.  The PROM address can be found with MacsBug and some
knowledge of what the ethernet address really is.  The ethernet address
is often on a sticker on the card somewhere or visible through a control
panel (or by sniffing the network).  It's a 6-byte number--something
like 00:80:2e:89:b8:db or some such.

Actually, hasn't someone put together a page on how to track this info
down?
