Ok, I'm now at a wall. I added a chunk to the top of
wacom_init_input_dev that prints out all of the details from the
wacom_wac features struct, and here's what my dmesg looks like.
I loaded the module, and this is what printed out:

During initial module loading, when it says "USB disconnect", my 0093
device disappears and then is replaced by the 0094 device.
I've got no idea where to go from here. Perhaps the generic wacom
interface that this driver uses isn't the same as the ones the other
devices are using? Without interface specs on my tablet, I'm at the
fringes of my experience, I've never reverse-engineered hardware
before.
