Both the Apple2 and C64 Contiki builds were done with recent nightly
snapshots of cc65, not a release version.

At least the CVS head for the Apple2 compiles fine with the cc65 of
yesterday ;-)

You are right. It should conceptually work but there are quit some
details keeping it form actually working:

- The API to the cc65 serial drivers changed and the Contiki SLIP code
wasn't updated yet.
- In opposite to the Ethernet card drivers the serial drivers are
interrupt based.
- The Ethernet cards have Onchip-Buffers for several IP packets, while
SLIP needs an additional buffer in main memory for collecting the
bytes until the packet is completed.
