Whatever logic you are doing in the kernel now to figure out which firmware to
use you can just as easily do in the kerenl and trigger it by sending a devd
event. You could have the userland side do an ioctl to get the type of
firmware the driver wants for example. There is _ZERO_ reason that you have
to do this in the kernel. You can move this logic out to userland and be
much more robust in the process. As it is, trying to do VOP_READ() in the
resume path is going to greatly diminish the robustness of suspend/resume.
Moving this to userland is not a hard problem.
