Well, depending on the point of view, it's a regression or a feature ;-)
in kernels pre-3.2 IIRC, this device used the embedded mouse interface
(so the double click "worked"). Now, it's using the generic
hid-multitouch driver, which means that it forwards raw multitouch
events to the upper layers.
The problem relies in the upper layers and not in the kernel: nobody
took the time to code a X.org driver that handles true multitouch
direct devices. You can eventually use the synaptics one, but you will
have to deal with absolute/relative coordinates, and the last time I
played with it, it was not convenient as I was not able to make GDM
use the absolute coordinate system (I kow I should have patched the
synaptics X.org driver).
