The sources are of course public, because the module links to the kernel,
IBM provides the source code for all Linux kernel modules under the GPL.
I just never included them in the kernel tree because the user interface
provided by the module is not suitable for upstream integration.

I believe that the PDT package comes with a copy of the source which
is built against the installed kernel when you install PDT, and it
should work with most recent kernel versions.

If the installation procedure is different, Uzi can probably point
you to the download URL for that module.
