Dual licensing avoids some confusions, it also removes the worry about
possible unanticipated incompatibility. Right now if a court somewhere
says "Hey you know what - BSD and GPL are not compatible because XYZ" the
fact it is dual licensed avoids problems.

Which then creates the risk question. This *has* happened before although
not with a court. Long ago the FSF used to maintain the fiction that
advertising clause BSD was GPL compatible. When the lawyers looked at it
in detail they decided this was not the case and also came up with some
fun abuses to demonstrate the point.

It only really matters if you are trying to be clear about dual use code
- for example some of the wireless code shared with BSD and the DRI code
where it's intentionally available in both universes. At the time some
folks wanted it to be clear their code was dual licensed and didn't want
to tag it "GPLv2". That may well in truth be more about politics than law
but it's hardly unreasonable to respect authors requests when they can
easily be handled.

So just mark your modules "GPLv2"

Feel free to change all those you are the sole owner for, but for
anything else go via the legal team of the relevant company and/or get
the owner to provide the change with appropriate sign off.
