Looking at the code, no intermediate .xkb file is created to disk; it's passed directly from memory to xkbcomp.
Btw, if you want to experiment more directly, you can snag ubuntu-12.04-dvd-i386.iso.torrent (or ubuntu-12.04-dvd-i386.iso) from http://cdimage.ubuntu.com/releases/12.04/release/ and burn to a USB stick using USB disk creator).
