When you run the buildinstall script from anaconda-runtime, it builds the install images by going through the rpms and pulling things out of RPMS.. it pulls the X stuff out of the X rpms, uses the glibc rpm, and a few others. It also needs a kernel, so the kernel-BOOT rpm is in the tree so that when the images are being built, the script can pull the kernel and whatever modules its configured to include out of the kernel-BOOT rpm. If the rpm includes more modules than are actually used, my guess is its done so they only have to build the rpm once (a full rebuild of all kernel rpms takes a while), and can then easily changes the modules being used just by tweaking the scripts.
