Yes. The primary reason is that it is more consistent with the rest of
the operating system. powerd also uses sysctl's instead of a character
device, for example.

The ideal solution would be to integrate it into vidcontrol, calling
some kind of ioctl on the TTY/consolectl, but syscons is too brainless
to know anything about hardware specific features.
