This should be fixed in rev 3068. (Thanks, Romain!)

We got this sorted out working together on IRC. We first tried to get 
pam_console running, but apparently that is more of a PITA on Gentoo than 
it's worth, so Mike resorted to the old-school "usb group" method together 
with an edit to the udev configuration to make the devices owned by root:udev 
with 0660 perms and this works.

This is a configuration problem we can't do much about within libticables or 
TiLP. On distros which configure pam_console by default (Fedora and a few 
RH/Fedora derivatives, possibly including Mandriva), this can be solved 
automatically (and in fact my libticables2 RPM does it), but on other 
distros, manual configuration is unavoidable. So if you have this problem, 
blame your distro for not setting up pam_console properly by default.
