Currently, GPL'd source has not yet been released, however, discussions with live humans at the Linux Section of TOSHIBA DIGITAL MEDIA ENGINEERING Corp. have been started. A list of GPL licensed sources have been provided, in list and “block diagram” form.
As of 2010-10-6: I've been informed that due to Toshiba's process, their official method of providing GPL source code is via data CD-R by airmail only. I've been told to expect that it may take 2 more weeks - unsure if that's the date when they'll ship, or when to expect it.
