That's only the MAC, you need a PHY too. 
Better to use a combined MAC/PHY, of which the CS8900 is a good choice (SMSC
also do some in the LAN91C family).

Phil: I'm not convinced about the address decoding on the CS8900, surely
it'll be permanently driving the bus?

Others: the 68B54 is still fairly easy to obtain (subject to silly MOQs),
and Beebmaster has ~100 readymade modules available anyway,
