Yup, it's the gcc --version that makes the difference.  GCC 4.2.0 couldn't
boot past the grub screen, GCC 4.2.4 made it to the login prompt.

The only config changes were imposed by the make script:

Posting the complete patchset RSN... (or tomorrow am so I can test some
more configs and functionality.)

Thanks,
Mike
