Ok, alfa nx kernel

#
# AR724X -- Kernel configuration file for FreeBSD/MIPS for Atheros 724x systems
#
# This includes all the common drivers for the AR724x boards.
# Since the AR724x boards tend to have minimal flash (sometimes 4MB!),
# the majority of the kernel framework will be built as modules.
