I am looking at doing something very similar with the AT91SAM7S chips.
 Like the LPC312x parts, there is no external data bus.  I think this
is the biggest issue.  It means you will either need to add a serial
to parallel interface chip of some sort (possibly an FPGA) or you will
have to bit bang the bit IO ports to talk to the Ethernet chip.  

The more I think about this, the more I like using an FPGA to provide
a fast serial port to the ARM chip and a parallel port to a LAN91C111
chip.  I am discussing this in the AT91SAM7 group.  I expect most of
this discussion will be applicable to the LPC21xx chips too.
