The provided-with-stock-dtb pin is: <0x40> which is P9 pin 15.
I use the only "free" pin on P8 or P9: <0x7c> which is P8 pin 26
There are various maps/charts/lists around with the pins. Just decompile
/lib/firmware/BB-BONE-GPS-00A0.dtbo and fiddle if you want a different
pin. The Debian relases come with dtc, I don't know about Angstrom.
