Drivers are not supposed to know about bootup or initramfs issues. If they want, they can disable the timeout, and wait for userspace to handle the request any time later, but they should not try to be smart here. Currently, firmware requests are cancelled if the firmware isn't found, but that's a userspace issue, and nothing the kernel should try to work around.
I can not agree more. I prefer to keep my driver happily unaware. I will just take the firmware loading away from the module init path and stop worrying about userspace issues ;-)
