genfb requires firmware help to set up a framebuffer and it needs  
machine dependent code to tell it how to use that framebuffer  
( basically address, geometry and colour depth ). On most machines the  
firmware will only setup one console device, be it a serial line, a  
framebuffer or whatever.
That said, the check is probably overly strict and should go away,  
instead we should look for device properties and bail if we don't find  
what we need.

have fun
