Is your volume exported to the network? If you export it with
some data-only thing like NFS, the resource capability is unseen
by the client. Then, the ._files are created even on HFS+.

See, what you could find in the OS X Development @ OmniGroup

The ._file is AppleDouble format (the non-data-fork part).
It is NOT just a plain resource fork in a data fork. It also
includes the other filesystem metadata.
There is plenty of documentation about AppleDouble on the web.
With some luck, the ._file stuff is somewhere in Darwin sources,
but I didn't have a look yet.
But I suppose that the ._file also contains other metadata...
in that case you'll probably have to extract the resource fork
part first somehow.
You can easily see this if you copy data-only files with the
Finder. Then, the Finder creates a small (50 bytes?) ._file for
each of them.
