Complete install of rawhide-20080510 (9-RC1) reveals two bugs:
1) netfs occurs before NetworkManager, so NFS filesystems don't get mounted: BZ# 445966
2) system hangs on diabling quotas during shutdown BZ# 445961
Still can't make askmethod or method= work when stage2= is present.
Otherwise things are working after workarounds are done. Specifically, NetworkManager is properly handling the wired ethernet, and SELinux is not getting in the way of normal operation.
