So the first thing the attorney would have to do is convince the judge that
the definition of a term from patent claims means what you are claiming it
means in software licensing claims.

Why is because the definition you have been pushing here is anything that
results in a "unitary" result. That's flawed (it's actually quite insane
IMNSHO, since the major point of my last email was that *damn near everything*
in the computer world results in a "unitary" result, including the glibc ->
kernel syscall interface Larry mentions in his email, the module loading
interface that the kernel exports, etc. The point of my last email was
largely that what you are calling a "unitary" result, is in fact what most
people call an API). To quote Larry, it would take roughly 30 seconds to get
that definition of "unitary" result thrown out as overly broad.

Yep, that's pretty much what it is. The firmware is what actually implements
the API on the device we are discussing. The driver interacts via said API.
The firmware is actually an opaque object that could be replaced with any
other firmware that implements the same API and things would work the same.
The downloading of the firmware is just one step in the initialization of the
device and is not dependant on any given firmware version or release. The
placing of the driver that downloads any valid firmware to the device (or
invalid for that matter) and the firmware itself in the same .o is a matter of
convenience and is merely collecting two individual parts into a mass.

You missed the point. The firmware is an opaque object to the driver, not an
integral part of the driver. Read above.

The current driver knows where the firmware is by #include'ing it in itself.
That is, in and of itself, a means of locating the firmware. You could
replace that with a code snippet that loaded the firmware from a file on disk
or on an initrd and read it into the same data format that the .h file
presents the firmware in. That would, in effect, tell the driver the new
location of the file (you would again have the location hard coded in the
driver).

And while that's an interesting topic, my original statement, and the only one
I am arguing, is whether or not the .o is a mere aggregation or is it
something more.

While I may be moderately intelligent, I am not Ms. Cleo, and me and my Tarrot
cards are having a hard time discerning an intent on the part of the FSF. Why
don't you ask them since they are the only ones that can explain their own
intent. Or better yet, who cares about what their intent was, what matters is
what is actually written in the license and how a court will interpret that
license.
