Have you seen Uzi?

http://www.dougbraun.com/uzi.html
http://www.cpmclub.de/zeitung/seite5.htm
http://uzix.sourceforge.net/

It's a SysV Unix kernel for the Z80, intended to run on CP/M machines.
Okay, it's a Z80 and not a 6502, and the 6502 has certain unique issues
with multitasking or running C (non-relocatable/fixed
size/fixed-location stack, ugh), but it might be interesting to look at.
