The only line of attack I see right now is an inadequate one, which
basically involves taking out libselinux.  Attempting to do so evokes
the following:

[root localhost ~]# rpm -ev libselinux

Which I think could be successfully done with a force and nodeps, as
long as you have selinux=0 on the grub boot line; however even if you
did so this still wouldn't address the presence of the selinux modules
in the kernel.

Selinux=0 may completely evacuate all selinux code from the boot
process.  Then, on the other hand, it may not.
