If the only difference to your old setup is the ethernet driver, than 
ethernetif.c should be enough to change (given that it worked correctly before 
:).

There's a skeleton ethernetif.c provided with lwIP. This and its comments are a 
good base to start your own driver. If that's not enough, have a look at the 
other drivers (there are some in contrib and some are listed in the lwIP wiki - 
or on the savannah download page) - however, be aware of changes from old lwIP 
versions and don't copy too much from old drivers since that might lead to bugs.
