It seem to be fairly easy to drive over i2c, somebody is already hacking something afaik. The basic idea is you can do 4 bytes reads from it, those return 2 16 bits values for the 2 light sensors and you can do 3 bytes writes to it, the first one beeing 0x01 and the 2 other ones giving a light value to lite up the kbd (the range seems to be around 0...0x1000) Ben.
