Two things came up in the effort of figuring out why the modem crashed the entire system when being restarted; the first one solves the actual problem, in that it's not possible to reclaim the main modem firmware region unless the modem subsystem is running - causing the crash. The second patch aligns the firmware loading process to that of the downstream driver, which seems to be a requirement in 8974 as well.
