devd deals with device_t things, not dev_t.  Typically, but not
always, there's a device_t -> dev_t naming convetion.  With the
keyboard stuff, /dev/kbd* isn't a real device, but a virtual one
(well, there are many folks named differently that attach to it).

No.

There's nothing similar to /dev entires coming and going in devd yet.
I plan on implementing it when I get some free time.
