Yes and no.
We already have removable devices in the tree. CardBus, PC Card, USB
and Firewire. Right now the drivers take liberties and chances and
there are a number of ugly races that rear their ugly heads. This is
an effort to clean that up and make things totally safe in all the
cases that we can think of, and to document those areas where we
can't.
There's no specific plans on my part to implement the hot plug state
transition and deal with it. People have raised their hands in the
past to work on it, but so far no one has made significant progress in
public view.
