I agree with Bjorn that it is a slippery slope for the kernel to try to be human friendly,
and that the kernel should just give the raw names and let an application translate them.

I think my original point was somewhat mis-interpreted.
My point is that when the kernel has _no_ PNPid to use to describe the device node
and we have to manufacture a string anyway, that we might as well manufacture
a string that a human can read.
