[Offtopic] Good Morning J.-S(when this is correct in your timezone).
To reply to your personal questions: All issues you are encounter like suspend or backlight or sound or fan or wireless or ... well, all hardware driver related are primary problems of the linux kernel. You have pointed out that there are less problems with kernel 3.2 and kernel 3.2 based distributions, but even this bugs occures with Ubuntu 12.10. -> The cause for this is that Ubuntu 12.10 based on kernel 3.5.x and what you obserse are called regression bugs(a bug that is induced by programming activity on further versions and causes functionalities to break that work in a privious version). Unfortunally this happens from time to time and it seems that it hit the the distance from kernel 3.2 to kernel 3.5 hard as you discribe. There are causes to tell for, but that would overwhelm the frame of a bugreport. To get this all fixed you do not have to do downgrades. You can do sepatated bugreports for all this issues, but this is also the drawback for you on this. Many work and not only with the reporting(report for linux itself from the computers are affected: ubuntu-bug linux). The standard workflow is reporting -> asking (you) to install the very latest kernel from special ppa(manually!), which is in moment kernel3.7rc1, - > if it do what it should do a kernel bisection - > if it not do what should report upstream to kernel bugtracker. On linux bugtracker is also a dropdownfiled for regression bugs. That for short and simplyfied on this. The special workflow may vary. As I pointed out this is very elabourious to you(complicated process when you do the first time and takes hours) and you might feel more comfortable with using Ubuntu12.04.1. On the other hand you are very welcome to do working on the linux kernel, because there are not so much powerpc people arround and you can do with your work direct help for this people(and make Linux at whole better; or not so buggy). The problems you encounter will not go away(most properly for the most of them) with the time for Ubuntu12.10 Quantal, because the kernel version3.5.x will not change in the livetime of it(with the exeption of patching e.g from bisection -> see above). The next newer kernels will be incoporated in Ubuntu13.04 development. As you can see I have marked this as offtopic, because for the most other readers here, this will be not of interest(save their time). greetings melchiaros Hope my expanations help a bit on your desicion what to do.
