Actually the kernel is run with both the Live CD and the alternate
installer, its just that (as you mentioned) different parts of it are
used with each installation method.

I still don't think there is sufficient information to determine this -
its entirely possible it crashed while during the boot process.
Removing 'quiet splash vt.handoff=7'[1] should produce more output
about the boot process and help determine where the issue lies.
