Since 'test' is a throwaway branch anyway, might it not make sense to
clone master to test and then rebase satadev onto it? Thus you would end
up with the linear history:
  o---o---o---o---o---o---o test (satadev')
  |           |
2.6.17      master

You know that master works and satadev' doesn't, and the bisection is
simple. After you find that bug, you can throw away the test branch.
