What I meant is that udev creates the /dev/lp0, /dev/parport0, /dev/lp1, ..., /dev/parport3 nodes by looking at /etc/udev/makedev.d/50-udev.nodes instead of actually detecting the ports. In the 50-udev.nodes file it says "These device have to be created manually" and proceeds to list several items include lp0. At least that is what happens in version 0.58. Does it make sense now?
