FTR:
Flashing original firmware together with emmc, then - without reboot - flashing openmode kernel, copy modules to phone, depmod, flash NAT enabled kernel, did the trick

# flasher -F org.img -F emmc.img -f
# flasher -F org.img -k zImage-2.6.32.54-dfl61-20121301 --flash-only=kernel -f -R

copy modules to phone (/lib/modules/2.6.32.54lopan-dfl61)
depmod -a 2.6.32.54lopan-dfl61

# flasher -F org.img -k zImage_lopan --flash-only=kernel -f -R
