A workaround in Fedora 15 (posted in another message to another list so you may not have seen it) is to use upstart instead of systemd for startup (systemd requires features only found on newer kernels). In the kernel boot line add "init=/sbin/upstart" and of course make sure you have the upstart package installed.
