Comment 9 for bug 1055644

Ok, implementation based on Mathieu's suggestions is posted as
https://code.launchpad.net/~pfalcon/linaro-image-tools/snowball_dts_tweaks/+merge/129419

This bug however doesn't list specific values to use (nor text at https://android-build.linaro.org/builds/~linaro-android/snowball-jb-gcc47-linaro-tracking-open/ does), so please advice about them.
