replaced linux kernel config

the previous config was broken ->  kernel freeze, serious errors at bootup

(perhaps I shouldn't have disabled all those unknown kernel options. duh.)

let's get back to the roots:

cat arch/arm/configs/bcmrpi_defconfig \
  | sed -re 's/^(.*)=m$/# \1 is not set/' \
  > board/rpi/linux-3.2.27.config

hopefully this will be better
