The Toshiba Z30 is a very nice laptop and works out of the box with Linux. Two things can be fixed however:
enabling the mouse wheel emulation for the pointing stick
making the touchpad enable/disable hotkey (Fn+F9) work
they require patches to the evdev driver due to Bug#11227 and #39174 which are unlikely to get fixed for X11. The code-remap patch is provided by Gianni Ceccarelli. The patch for mouse wheel emulation can be downloaded from this page.
