No.  

The DEC tablet is currently supported as the X pointer device on the 
DS3100/2100 and the DS5000 in Ultrix 3.1D and 4.0.  

The active region of the tablet surface
is mapped onto the root window coordinate space; the tablet coordinates
are scaled in x and y and translated to X window coordinates.  Thus the
pointer at the bottom right hand corner of the tablet moves the cursor to
the bottom right hand corner of the screen, etc.  No provision was made to
provide access to (unprocessed) absolute tablet data.  In order to access
the 4th button on the pointer, you must start the server with the command
line argument "-btn 4".
