I would say to just disable IRQs while loading firmware.  Almost every
server I maintain has some vendor driver which generates a "many lost
ticks!" message on load.  As long as it's only done at module load
time it should be fine.

For anything ~10s or more, you'll probably also need to call the timer
update function to prevent soft lockup warning being generated.

Of course the best solution is to just get the driver into mainline.
