Something like the following should work, if you haven't already got it 
figured:

diff --git a/drivers/serial/8250_pnp.c b/drivers/serial/8250_pnp.c
index d3d6b82..c7b019b 100644
--- a/drivers/serial/8250_pnp.c

and then just make sure that you have CONFIG_8250_PNP enabled. After 
that, it should just appear as a touchscreen. You may still need to 
perform some handshaking in the protocol interaction to get it working, 
but ideally that would be done in the X driver.
