The thing closest to it which is actually in linux kernel (2.1.x)
is "Capabilties". But it is not a fine grained as you ask. It would let
you give privilage to 'access ports'

IIRC.
The thing you talk about was 'chown port' patch, which used to
map ports onto filesystem and use chown to change them at will.
I did not made into kernel
