As I understand, it doesn't do any > power-management stuff anyhow. My monitor (Iiyama Vision Master Pro 21) turns its power off as soon as it realizes that the screen was staying black for a certain amount of time (configurable). It hasn't anything to do with power management stuff, since I can also reproduce it by turning the cursor off and then typing "clear; sleep 10000000" in my shell. That's why I appreciate the kernel console blanking. Although I suppose it would do the same if you just cycle the colors, since the monitor shouldn't notice the difference. But you would have to cycle the colors to black, I guess. "very dark grey" would probably not be enough. And then I see no point in cycling the colors instead of blanking.
