Install the kernel sources in /usr/src/sys. Roughly speaking the kernel 
build process works this way:

1) go into /usr/src/sys/arch/pmax/conf
2) use GENERIC.pmax file there as a config file and invoke config
   to create your makefile

3) go to /usr/src/sys/arch/pmax/compile/GENERIC.pmax
4) make depend
5) make

Read the man page for config for more details.
