I just use:

git-send-email --to openmoko-kernel at lists.openmoko.org --compose
<patch directory|patch file>

There's a good argument for adding --no-signed-off-by-cc, especially
when you are borrowing patches from non-Moko trees where there may
already be SOB's on the patch from non-Moko people.  This can reduce
noise quite a bit.

And as a matter of taste, I prefer to that --chain-reply-to is used...
at least with GMail, it makes it easier to see the individual patches
-- they tend to get lost on the thread otherwise.

The --smtp-server bits can be set up in your .gitconfig.
