Why do you need the user-mode helper anyway. This is all static data,
right? So why not cook up a firmware file in user-space once and put it
in /lib/firmware for the driver to request directly. Seems a bit
overkill to have a {e,}udev or whatever daemon running if the result is
always the same. Just my 2 cents.
