Yes, I'm porting lwip to Motorola 68302 (big endian too). No SLIP but an
interrupt driven SMCS ethernet controller 91C911. Compiling under
Linux/gcc (68k cross).

I'm using to latest cvs-sources! TCP, UDP, ICMP, httpd - all works.

I recommend using the _latest_ cvs-sources! In the past (since 0.4)
there are some changes for big endian and checksum calculation.

Caution with interrupt driven frame input! Avoid calling functions which
are semaphore blocked -as netif->input()- directly from interrupt!

Hope it helps
