That usually means your Video driver didn't initialize them. The words 
are defined as "defer" words, so they don't point to anything useful 
until a display driver comes by and initializes them. This allows one 
piece of code to be generic and callable from the ok prompt, while to 
unsightly innards are buried in the specific video driver that this 
system has loaded.

It sounds like your display driver didn't initialize them.
