do you mean that the driver itself opens a file?
yes, it's quite practical that the driver loads the firmware by
itself. but it won't work if the driver is built in the kernel,
because the filesystem might not be mounted yet.
so, a loader binary would be more feasible.
(and, we can call such a binary conditionally according to the
kernel config like request_module() calls modprobe.)
