I think you're definitely _with_ the current on that one.

They don't even need to be shipped with the kernel tree. You can set
CONFIG_EXTRA_FIRMWARE_DIR to point to wherever you keep them
(like /lib/firmware) and it'll pull them in from there. That's _why_
it's useful for drivers which would have required an initrd before, and
which don't have their firmware shipped in the kernel tree.
