I was able to get the necessary .fw-files from the original Ubuntu-kernel source. To do this, I used the instruction of the Kernel|Git Guide to get the complete source on my harddisk. I changed to the directory /usr/src/ubuntu-intrepid/ and after selecting the correct kernel version, at the time of writing this

git checkout 2.6.27-10.20

I ran the command

make firmware_install

That's it. The firmware binaries will be created and installed properly in /lib/firmware/ where the driver modules can find them. With the next

modprobe keyspan

(actually this works only if keyspan has not been loaded before, or a

rmmod keyspan

has been issued), the necessary firmware-files are properly included so that the devices just work. Credits of course to all involved :)
