Linux on the Playstation 2

A source (who asked to remain anonymous, but is reliable) claims to have seen a Linux Port to the Playstation 2. He also saw a PS2 running X and KDE on the machine, running on the MIPS processor w/ 32 Megs of RAM. Unfortunately the information that is available is all written in Japanese. It would be sweet if Sony would make a free image available so people could boot Linux. If not, maybe someone else is up to the task? My PS2 is currently in Toledo (after taking what seemed like an eternity in Memphis). Damn fedex: I need to play Star Wars Starfighter and DOA2! If I boot Linux, can I count it as a business expense?
