Erm, but you've just shown us it in your config?  If you can't find the
options to set it, then something is very wrong.

It really, really sounds like you've managed to screw up your kernel
config.  The above behaviour suggests that you might have forgotten to
do a 'make oldconfig' at some stage ... also note that 'make config' and
'make menuconfig' might leave your .config files written slightly
differently.  They should have the same *contents*, ultimately, but
perhaps laid out in a different way.

Please persist in trying to get a Debian stock kernel working; this
sounds like your best bet.

Dave.
