Toshiba Portege Z830/Z835

Works mostly well with Ubuntu 11.10 out-of the box: the screen brightness buttons do not work after returning from a suspend, and default battery life is not great, but both these problems are solvable: see this page.

Bluetooth works, but you may have to press FN+F8 until bluetooth is switched on (it cycles between wifi, bluetooth, wifi+bluetooth, off). Some models don't include bluetooth.
