Is your source 8/31 or newer? 8/31 was about the right time to do the elf
upgrade. The cam integration was on 9/15. If you source that date or later,
you will SOL for running the 1502. Running CAM is NOT optional if you update
to current source.
If you are running current, GENERICupgrade does come into play, only used
for stable upgrades.

^^^^^^- this (make aout-to-elf-install) will install elf binaries etal
but your old kernel will still work.
