Only small add-on - in my mail archives I found this link 

http://www.nano-system.com/cgi-bin/cvsweb.cgi/freebsd/kernel/dev/gpiobus/

I looked over there in the past and probably used it as an inspiration. Also, 
there is lm75 driver able to work on gpio as well (i2c temperature sensor).

I still need to find my older work (or some traces of it) - for some reason CF 
used for debugging on WRAP does not boot any more, but I saved some images 
somewhere, so it is still possible, given some time is available...
