All three UARTs of the 2410 are in use (one for GSM, the other two
for GPS data and handshake (*)). You can't assing the UART to random
GPIOs.

(*) I.e., the 2nd UART is not used, but its RX/TX pins are taken.

You could of course try to dual use some UART. I wonder why LIRC
requires a UART. Does it use it to generate the 38 kHz carrier ?
