Installing it was a bit difficult since its module driver (from wacom-kernel-source 0.6.6) failed to handle events. So I had errors like:

wacom_graphire_irq: received unknown report #99

everytime I moved the stylus (Volito is in fact a crippled Graphire). Various howtos did not mention this, so after having used strace and friends, I found that there was a problem in the driver and commented out the faulty line and voilà ... a new shiny tablet!

Now I need to tweak pressure configuration a bit to produce better lines ... and of course to send a better patch to upstream.
