This was in fact what I was considering when making my initial post, but 
couldn't find any examples or drivers which do use sysfs and request 
firmware in this way and as you say, it's not pretty. However if it's 
considered to be cleaner by others (I certainly think it to be so) then 
I am inclined to use this method as opposed to the ioctl method 
suggested by Arnd earlier in the thread.

Arjan, could you possibly point me at any drivers which already work in 
this way?

Thanks,

Philip Downer
