I uploaded on Google Code the last version (0.2) of FreeJALduino documentation. It is in HTML and is easy to browse. Is a little archived offline site which can help you to get started with this board.
The name of the archive is "doc_v02.zip" and can be downloaded from this page. The jal_v02.tar.gz archive (from the same download page) contain the development environment for FreeJALduino board and is referred in the documentation as being "jal.zip" archive.
