Sorry Nial, afaik you're wrong.

If you take previously existing code you only need to assure it has a
GPL-compatible license to make a new work base on both a GPL piece and
this piece.
Instead if you make _derivative_ code, that must fall under the GPL,
otherwise you have no permission to use the GPL portion of the code
you're deriving from.

Adding a pre-existing portion of BSD code to a GPL project is not
deriving code, as it existed well before. Instead creating code as new
that depends on the existing GPL code is a derivative work.

Derivative works and other works have really a completely different
legal status in most legal systems.

Simo.
