Call me stupid if you wish, but can someone help me on how to make modifications to kernel-power source . I mean - every time dpkg-buildpackage is run patches from debian/patches are de-applied and re-applied making it impossible for me to modify actual code without some ugly hackery.

What is correct sequence/procedure? Any hints?

BTW what I am trying to modify is dspbridge driver, code from omapzoom git looks pretty similar to what we have in kernel. Maybe if I succeed I will be able to run 720p codecs from android.
