Как ускорить загрузку OpenWRT на TP-LINK TR3020?

Cобрал кастомную прошивку на девайс (статический ip + usb mount + samba). Выпилил кучу ненужных пакетов и добавил нужные для работы:

make image PROFILE=TLMR3020 PACKAGES="-kmod-gpio-button-hotplug -kmod-ath9k
-wpad-mini -ppp -ppp-mod-pppoe -iptables -ip6tables -kmod-ipv6 -firewall block-mount
samba36-server kmod-fs-ntfs kmod-fs-vfat kmod-nls-cp1250 kmod-nls-cp1251 ntfs-3g
usbutils kmod-usb2 kmod-usb-core kmod-usb-storage" FILES=files/

Время загрузки составляет 35 секунд. Нужно подшаманить хотя бы до 20ти. Как это сделать ума не приложу :(

Работает всё на ATTITUDE ADJUSTMENT (12.09, r36088)

Ответ на: комментарий от Black_Shadow

Он используется в связке с PS2. А там софт (OPL) грузится быстрее и не успевает подцепиться к самбе - приходится перезапускать всё. Поэтому и хочется ускорить этот «холодный старт».
