I am no expert on udeb permission rules but that looks to me like you want the owner *and* group set to lp, with a permission of 660. But looking at the output of ls above you get root as the owner. Anyway that's what it looks like on my setup as well. I haven't had time to work with the udeb permissions (don't even have a udev.permissions on my etch setup), but I only got it to work when I set the permissions to 666. I do that from a startup script now. Not very nice I know but it works. Let me know if it helps.
