As issues with the link power management are so controller specific, the solutions usually only fix one type. The last upstream changes added some framework to prevent bad effects only for a Nvidia controller. I would highly suggest to open individual bug reports for each controller. When doing so, could you please add the exact symptom (like whether the fs gets remounted read-only or whether there are only error message). Also try using medium_power written to the policy as described above. Does that work ok? And finally (if you are not already using a natty kernel) get the 2.6.38 mainline kernel from get http://kernel.ubuntu.com/~kernel-ppa/mainline/ to see whether by now that controller works. Generally when I asked about this upstream I got the impression that ICH controllers were supposed to work. Of course there are always exceptions...
