Cipher Brain has bought a Toshiba 6100 Pro to load it primarily with GNU/Linux. Please find here a few tips about setting it up.
Update: after having had a horrible experience with Toshiba Support, spread on more than two monthes, numerous phone calls, faxes and letter (concerning another notebook), and a lot of hardware problems with this notebook (including two power supply faillures in one month, broken display, defective hard-disk and keyboards problem), I’ve given up with Toshiba. I’ll let this information here, in the hope that it will be of any use to somebody.
Personally, I can’t recommend anymore usage of Toshiba notebook computers.
