The USB keyboard and mouse drivers are streams modules that are pushed on
top of hid devices to convert the USB HID protocol to the Solaris VUID
protocol, which allowed them to then appear as /dev/kbd & /dev/mouse
without requiring any changes to users such as the X server.
If you wanted the Wacom driver to appear as a standard mouse to X servers
and other users of /dev/mouse who don't know any better, you could do the
same, but if you only want it to appear when specifically looking for
a tablet, then I don't think any such module would be needed. (But then,
I've only worked on this from the X server side, never from the kernel
plumbing side.)
