The Toshiba Satelite a70 laptop is mostly compatible with Linux, at least Fedora. The only real big problem I experienced was getting sound to work. With speakers attatched through the sound outlet on the right side, sound worked, but not very well, and the speakers on the laptop I have not yet gotten to work. Also, the Atheros wireless internet card can easily be installed with madwifi, search simeandrews and you'll get some answers.
I can confirm that the Toshiba A70 will run Debian 3.1 sarge Linux v2.6.17.
In fact, I am currently running the Knoppix 5.0 Live CD version which I then installed to the HD.
I have also ran Fedora 2 & 3, Knoppix 4 on this laptop in the past.
I have at one time or another had the following pieces of H/W working under one distro or another:
1)Firewire/iLink - which is connected to both a DVD-RW & a no-name HD enclosure (with Oxford chip);
2)Atheros 802.11g - can connect to wireless router using madwifi, but gave up on getting WPA working;
3)internal modem - got it working a while back on Fedora 2 using slmodem(?), haven't tried it lately with Debian, but I think it should work also;
4)sound + speakers - they work under Knoppix 5 (and Debian 3.1), but I had to fool around with drivers and amixer to set the speaker volume. I also recall I had it working under Fedora 2 in the past;
