I have done this approach for both plated and unplated slots, i.e.
drawing lines where the slots will be and also putting a hole/pin at
both ends of that line. Post processing of this is simply exchanging the
hole at the beginning of the line with an M15 command, followed by a G01
(with coordinates) command, followed by an M16 at the hole/slot at the
end of the line. Sequence is ended by an M17 and finally M30. For
circular tracks (or arcs) G02 or G03 could probably be used in a similar
fashion.
There is a patch for gerbv for adding G00/G01 commands:

I would love to see slots supported by pcb!
