Here are the missing pieces for udevtest. A simple man page is added, the blacklist is removed, cause it can't work without having a subsystem. The Makefile removes all manpages now with a uninstall and installs udevtest in /usr/bin/. Any old version from /sbin/ should be deleted by hand. The only expected argument is the sysfs devpath, here I changed it to be more tolerant to the input. The path may now be specified with or without a leading slash and optionally with the /sys moutpoint prepended. I hope this will end the confusion about the use of this program :)
