So here is the latest testing update...

The only testing that we were not able to do was the IPMI testing,
because of the lack of resources.  All other testing passed.

While all other testing passed, I am concerned about not being able to
test whether or not this change affects the ability to pass IPMI
traffic.  I am not sure if the "gain" of using request_firmware() out
weighs the potential risk that IPMI traffic may be broken with this
patch.  I guess I wondering what the gain is in using the
request_firmware() function?

>From past experience with IPMI traffic and the e100, the loading of
the microcode in the correct manner greatly affected whether IPMI
traffic would pass or not.
