My device seems to be blacklisted by hid-core.c:
 static const struct hid_device_id hid_blacklist[] = {
 [...]
 { HID_USB_DEVICE(USB_VENDOR_ID_DWAV,
   USB_DEVICE_ID_DWAV_EGALAX_MULTITOUCH) }, [...]

and supported by hid-egalax.c:
 [...]
 static const struct hid_device_id egalax_devices[] = {
        { HID_USB_DEVICE(USB_VENDOR_ID_DWAV,
                        USB_DEVICE_ID_DWAV_EGALAX_MULTITOUCH) },
        { }
 };
 [...]

Although I'm not 100% sure if the sources I was looking at corresponds
to the version of the ubuntu stock kernel images (at least both is
v2.6.35, but I don't know if the ubuntu kernel images include other
patches)
