Aha. That's the part I was missing. :)

And apparently I got stuck between the unreleased tool to split the file,
and the release of the new style data file.

Anyhow, it appears the firmware_request() was just a bullet loaded in the

CONFIG_FIRMWARE_IN_KERNEL=n :)

The behavior is explained, and presumably Intel will eventually release
a method of getting the new-format bits, and all will be right with the
world (or at least this part of it.. ;)
