So if you look a the output of modinfo for all of the modules that your system needs, you will see a "firmware" line that shows the name that your hardware needs for that specific driver/module. Just take those specific files and put them on your disk and you should be fine. Note, I think tools that generate initrd images can do this automatically, so perhaps you should look at what they do as an example for this.
