i've compiled 2.6.27.2 source after having patched it with your today's
patch.

it works! i.e. i can navigate (w3m kernel.org) and update (apt-get
update)

i send you anyway the usual tcpdump as in previous msgs, should it be
of any help.

do you want me to provide some more commands output?

waiting...
