This is a first step in allowing people to by-pass udev for loading device firmware. Current versions of udev will deadlock (causing us to block for the 30 second timeout) under some circumstances if the firmware is loaded as part of the module initialization path, and this is causing problems for media drivers in particular. The current patch hardcodes the firmware path that udev uses by default, and will fall back to the legacy udev mode if the firmware cannot be found there. We'd like to add support for both configuring the paths and the fallback behaviour, but in the meantime this hopefully fixes the immediate problem, while also giving us a way forward.
