To save anyone else from tearing out more hair than they can afford, be aware that the current files rpi.dts (r276161) and bcm2835.dtsi (r278915) have not yet been updated for the Raspberry Pi Model B+ GPIO pin mappings.

One consequence is that your dmesg will show:

gpioled0: <GPIO led> at pin(s) 16 on gpiobus0

when in reality the ACT LED is at pin 47 which the bcm2835.dtsi file shows as READ-ONLY, so it cannot be changed by gpioctl as one might otherwise expect.
