Well, Toshiba Japan has a Linux developers' page (in Japanese): http://linux.toshiba-dme.co.jp/linux/jpn/develop.php3 According to that page, their mail address for requests from developers is: linux@toshiba-dme.co.jp so if you don't get any satisfaction from Toshiba USA/Europe/wherever you're living, try asking Toshiba Japan (they do ask that you be specific, so if you send them a request, make sure to state exactly which models/chipsets, etc., you're interested in, and remember that they might take a while to reply to email in English). They do seem to be quite good lately about releasing documentation - Dag Brattli got some info on the IrDA hardware they use, and the Japan Linux Association has got docs for the ToPIC PC Card controller out of them, too. The only time they've actually turned someone down (according to that page, anyway) is when the hardware in question included third-party technology. Bruce
