This allows ASUS Eee Slate touchscreens to work.

I do not have one of these to test the patch but I helped a user
debug why his new touchscreen was being treated as a touchpad.
He reported success after adding this ID.

The patch looks good.

I'm sending this since I'm unsure status of patch to auto-assign
multitouch devices to hid-multitouch. That would probably have
solved issue as well.

Well, as of today, the auto-detection is partly included in 3.2-rc1:
the generic hid layer will release the device (ie, it's not needed
anymore to patch hid-core.c while adding a multitouch device to its
list), but hid-multitouch is not capable of handling it after the
release of the generic part.
BTW, egalax devices need a special handling, and we may have to add
them one by one.

Alternatively, we could use:
 +       {  .driver_data = MT_CLS_EGALAX,
 +               HID_USB_DEVICE(USB_VENDOR_ID_DWAV, HID_ANY_ID) },
but that's hoping that DWAV won't do any other things than multitouch panels.
Jiri, have you an idea on this?

Cheers,
Benjamin
