Yes, the idea is to be able to disable misbehaving built-in modules
from the kernel command line. The alternative is of course to disable
the code using the kernel configuration system and rebuild the kernel.

Say a kernel shipped with your favourite distribution crashes your
machine during boot-up - wouldn't it be nice to be able to just
disable the problematic module from the kernel command line instead of
(1) getting the config, (2) getting the distribution-specific patches,
(3) rebuilding the kernel. And if you are lucky you need to (0) setup
a cross compiler and (4) get your hands on a suitable initrd.
