Hexxeh,

I think this'll be fine, but for Chromium OS changes, we've switched to Gerrit,
so you'll need to resubmit with the new tool.  :-(

Some of what you'll need to do is documented here:
  http://www.chromium.org/chromium-os/developer-guide/gerrit-guide

It *should* be as simple as this:
 1) Get a Gerrit account as described at the link.
 2) Upload the CL with a command like this:
    cd src/scripts; repo upload .

I'm afraid it's not as well documented as it ought to be.

Note that the change will need to be on a branch all their
own that tracks cros/master as the upstream branch.

Also, 'repo upload' uploads each commit on the branch as a
separate CL.  That has two impacts:
  * If you need to make changes to upload a new patch,
    you'll need use this:
      git commit --amend
  * When you initially upload, the branch should contain
    just the change you want to make, and the commit
    comments need to reflect the final form.
