well, the change was driven mainly since i couldn't have
tcp accept working with recent mainline kernels until i enabled
CONFIG_SYN_COOKIES. With CONFIG_SYN_COOKIES tcp accept works
again, will try to go deeper a bit on this since i believe
tcp accepts should work also without CONFIG_SYN_COOKIES.

I also had the chance to "diet" a bit kernel size and enable
sysfs gpio.

I'll resend v2 later.
