Set the DETECT_KBD bit (0x08) in the configuration flag of syscons,
and its probe routine (scprobe) will report failure if keyboard reset
fails.

As for the display adapter, syscons assumes there always is a graphics
adapter.

I always thought these are design decisions. We have to ask Soren 
exact reasons why these decisions were made.
