As long as you did not already include code with a limited license (e.g. GPL),
I see no problem with the Sun CDDL sources.

The netboot ("inetboot") was available for intel and sparc for Solaris 9
Check /usr/src/psm/stand/boot/sparcv9/Makefile*
If we get inetboot to compile on PPC, we need no GRUB.
