There is a good chance that you can just copy the files in this
directory from RELENG_6 and it will work on RELENG_6_2 (since those
two versions are still close together). You will also need some of
the changes in sys/conf/ to "glue" it into the kernel build, which you
can extract from the CVS (see e.g. cvsweb). Or you can copy the
sys/modules/${whatever} directory too and it should be buildable as a
standalone module.
If you are unlucky then the driver may rely on changes made after the
release of 6.2 and you will have to either back-port those changes too
(or just run RELENG_6).
