If you do cat /sys/bus/pnp/devices/*/id, do any of them look plausibly linked to the tablet device? If so, add the id to drivers/serial/8250_pnp.c, build it, see if that binds and gives you a serial port and if so send a patch. -- Matthew Garrett | mjg59@xxxxxxxxxxxxx - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
