Looks like I should subscribe again to cvs-all, ok, will read.

I do read man-page before.
Actually, I don't want bt kbd work under dbb, But I don't want to loose
at keyboard for DDB when I use bt keyboard for other (not DDB) input.
This was my point.
As I understand valid (and only) usage of vkbd is
1. start user-land software feeding vkbd with events (probably from
different sources atkbd, ukbd, btkbd)
2. change syscons input to vkbd
in this case any enter to DDB will stop keyboard processing at all.
my idea was just have hook (probably ng) to be able shortcut vkbd and
atkbd without user-land software.

No, as I said before I just want be able to enter DDB with at keyboard
when I have use bt keyboard.
I do not try to flame at all, just supply ideas.
