LCD display on Cisco uBR10K

Docs say
"The LCD module provides real-time operating status and configuration information for the chassis and line cards. The buttons below the screen provide a menu system that allows you to display different parts of the system configuration without using a terminal."

But as far as I know with any recent linecards/PRE, it does nothing

I'd been told by one of our Cisco reps that it was an idea Comcast wanted int there, so the white shirts could look at a cmts and see stuff without having to log in. She didn't know if it ever worked.
