Sounds like you didn't enable the tmpfs security labeling support in your kernel .config (CONFIG_TMPFS_SECURITY). That would prevent setting/getting security labels on the tmpfs /dev managed by udev, and thus /dev would be inaccessible to most processes.
BTW, 2.6.13-git11 obsoletes this option and the DEVPTS_FS_SECURITY option, as it includes the generic VFS fallback for security attributes.
