I've added code into debian-cd to generate images with firmware on the
first CD. Add "FORCE_FIRMWARE=1" in CONF.sh. I've also tweaked the
build scripts so that we'll start generating them. I can see that I've
got all the firmware debs in /firmware in the ISO, but I don't see any
feedback to suggest that the installer is picking up on them. Test
images available at


in case anybody else wants to help testing them. I've still got a
couple more things to decide about these new firmware-included images
even once we've got these working:

 * where exactly to put them on cdimage (for now they're alongside the
   normal images)

 * how to describe them in the README on the disc. For now I've added:

   "This disc includes non-free firmware files to make installation
    easier on some systems. See http://wiki.debian.org/Firmware for
    more details."

   but I'm open to suggestions for something better.
