Things are getting now a little bit fishy. Before, I was using gnome and all the little daemons that come with it (even though I just prefer a plain window manager), but, as I mentioned before, it didn't matter if I pressed the power button on X or on a console. I had the gnomee power-thingy sounding like an alarm (an ambulance!) on me when I pressed the power button with Debian kernels 2.6.22, for instance. I compiled my own (this time, from kernel.org) 2.6.23-rc3, with many modules and subsystems removed (e.g., bluetooth, as this laptop doesn't have it) and I got the exact same behavior. If I booted, OTOH, with Debian's kernel 2.6.18, things were fine and the machine would go to sleep without any problems. I am now suspecting of some module that prevented the machine from going to sleep and I now using just a fluxbox as my window manager. This time, even with a 2.6.23-rc3 kernel (again, from kernel.org) the machine went to sleep normally. I did 13 compiles with git bisect and some of them were unsucessfuly compiled, which I am afraid that may miss the real cause if I tag them as being "bad" (which I did). (This was with just a bare minimum installation of Debian). The course of action that I am taking right now is to pull GNOME and see if my current 23-rc3 kernel has any problems and see which modules are loaded. If things progress well, I will incrementally include features on the kernel that I need (I left out, for instance, the Firewire subsystem, so that compilation wouldn't take more than an hour here, despite the fact that I do need Firewire support on the kernel) and see the point where things are not normal. Again, I am willing to test anything that is useful to getting PowerPC working as well as it should with the final 2.6.23 release. Please, don't hesitate to ask for any further information.
