But every existing application that uses (shiver) the kernel headers
will break after this change...

Geert, can you explain the whole story please ?

The story about the +1 or the story about the breakage?

The Story About The +1
----------------------
Since the VESA levels do not provide a way to blank (`make it black') the
screen, the +1 is introduced. Hence 0 means unblank, 1 means black screen,
2 means lowest power save level, and so on...

And make it black is usually done in software (by memsetting the screen with
the black color).  

Or by setting all color palette registers to black, if available, since it's
cheaper...
