'Phys:' field for keyboards (and other input devices)

[Andreas S. <an...@sc...>]

I think the dev->phys entry in the input layer is an important
key to associating a given keyboard with a certain VT (in
kbd_connect()). 

I see that for USB keyboards and for ps2 keyboars this field is
filled in nicely. But are there any other keyboards that are
valid as controlling keyboards (or in other ways desireable to
bind to a VT) that do NOT have a valid dev->phys entry?

about binding devices to VTs:

it is important to bind Keyboards to VTs to be able to start
Xservers on that VT. Mice (for X) can be configured in the
XF86Config. but it would perhaps be nice to be able to configure
which mouse goes with which /dev/input/mouse* device, which in
turn get used in the XF86Config. Do people agree on this or is
that unneeded featureism? Do joysticks need to be bound to
certain VTs, too? I would not know, I do not even have one. How
are they accessed?
