I agree and this doesn't mean it can't be improved. Just few points
here:
(1) * sysfs: isn't size/performance/political appropriate;
(2) * request_firmware() uses virtual memory for it's allocations, this
lead to additional kmalloc() dance, because 4-5 12bits pages in
size firmware (on some platforms, AMD64 included) cannot be sent
directly form provided buffer.
(0) and (1) were used in last GPL offtopic on LKML. (2) depends on (1).
I've proposed an idea without implementation, and still fight against
myself to do something. My early silly posts:

Alan, if you have some time to comment on my /dev/etab, i will very
appreciate that.
Thanks!
