email toshiba, and earth lcd... ask them for pinouts.
earthlcd has it on the list of screens they will buy, so they should know something about it.
toshiba should know something about it as well, cuz its their screen... send a picture of it if you can. then they wont be as likely to give you the crap about it being a re-seller item that they dont know anything about...
thats what i would do, since the google search i did came up with nothing helpful.
