Hmmm, there can also be another scenario.

Because, there is nobody in the team that is able to fix that (because nothing needed to be done around raw1394 - libraries were used), so maybe problem is not in ekiga itself, but in one of libraries that run "on behalf" of it. Maybe these libraries are not ready to utilize new kernel API or so.
Anyway I'll try to locate the problem.
