Well, the problem is that it is very hard to get the names for the
firmware images found in the binary.

What you could do is try to find a Linux driver and a Windows driver
with exactly matching FW versions and then use the names from the Linux
driver to extract the blobs from the Windows driver.
It would be pretty easy to write a script that takes a Linux driver and
its matching extract-offsets and extract-names and then create the
corresponding offsets for the Windows binary.
Please feel free to create such a script and I would be happy to
include it in b43-fwcutter.

A script to auto-generate the extract-info from a Linux driver is
already included with b43-fwcutter.
