Well, I think I am in position

@Pali, why is that filter needed in Maemo5 kernel, what problem/bug it fixes, or what functionality it adds? Who sent you the patch? Is it upstream patch?

TBH I think you should remove that from kernel-power at least until there is some information WTF is this animal(the filter) doing and who will support it (fix bugs) at least while KP is in devel.

Or even better - remove it constantly.

P.S.
And maybe you should re-consider your policy to accept patches from developers who cannot be contacted/don't want to help if some problem arise, thus leaving only me and you to fix bugs introduced by some random guy.
