Really, that logic sounds awfully wrong. Any /dev-caching and games with skipping selected subsystems at coldplug can never reliably work as you have found out. :) You should definitely go for devtmpfs instead of such needless and misguided hacks, if a plain "udevadm trigger" does not work for some reason. Good luck.
