Matching is done automatically when you load the kext manually or when
new hardware is added (if the kext is load already or in the Extensions
directory). You should not have to write any matching code yourself
(other then overriding the standard probe method to take part in the
active matching phase if needed).

Just make sure your plist entries are correct for both matching and
dependencies (dependencies vary by what your driver needs in order to
function).

The following is from a PCI based Fibre Channel adapter driver I have,
that only runs on 10.2 or later.
