I've written one, you might find it useful.  See:

        http://www.bdmicro.com/code/

See the 'diag' project.  The interesting files are:

        threads.c
        threads.h
        thread_swtch.S

Mostly C, the context switch routine is in assembly.  See the 'diag.c'
file for declarations and usage.  I've used this on ATmega128 mostly,
but I've also used it on an ATmega163.

Cheers,
