It looks like this one:

http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/arch/powerpc/mpc6xx/?hideattic=0&only_with_tag=netbsd-1-6#dirlist
http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/arch/powerpc/mpc6xx/Attic/cpu_subr.c?hideattic=0&only_with_tag=netbsd-1-6

1.6.2 was before the move to oea from mpc6xx.
