Yes, there is extra RAM on board, although getting quite tight now.

Uses the CS8900. Managed to write a driver for the Atmel and ported uIP
stack over. Unfortunately this is taking up a fair bit of room in the
firmware.  With hindsight it may have been better using one of the chips
with a built in stack that are now available - although it might not have
been quite so easy to implement one or two of the routing features that
we've done.
