This is the tactic we took, as I mentioned before, with an unreleased
update set of ISOs for RH 7.2 for Alpha.

1. kernel without LEGACY_START_ADDRESS is the ONLY one that shows in
   /etc/aboot.conf on the CD
2. kernel with LEGACY_START_ADDRESS is the ONLY one that shows in
   /milo.cfg on the CD.

I'll attach them both to the end of this...

It may be easier to just respin CD #1 with the two kernels...

It's really something you have to experience directly to appreciate...
