I have _no_ idea where in the code the guy found this stuff.  :-)

I haven't set up CVSweb, but you can just check out a couple of files.
The relevant ones are

osfmk/src/mach_kernel/ppc/POWERMAC/wd.c
osfmk/src/mach_kernel/ppc/POWERMAC/wdreg.h
osfmk/src/mach_kernel/ppc/POWERMAC/wd_entries.h

And you're right, I should set that up....  :-)
