The purpose of the nvram init script is to reset important variables
in-case previous firmwares crapped them up. It is something that has
been done since the first wrt54{g,gs} and is well documented.
I have my router over-clocked, so I have always kept a copy of
/etc/init.d/nvram inside my ~/trunk/files/ when preparing images as
too keep my settings. Openwrt is made for the lowest common
denominator, and since we have hacked on our routers we need to make
the appropriate modifications to Openwrt to allow them to stick.
