Good new, if I can say. I cleaned my build tree, updated my packages (one was
about gcc), redownloaded the firmware and recompiled 69e0b57: it now boots with
and without radeon.dpm=1. So, I'm closing this bug. One of those things must
have been the culprit.

I just have to test with rc3 now and hope for the best.
