    Well, I suspect the warnings are there for a reason, e.g. with 2.6.32-rc
    I also hear the fan regularly while I've almost never done before. So I
    guess the reason for it is that throtteling might have problems.

    I'll try. This is my main work machine (and I'm travelling right now),
    so any sort of bisection and testing will take a while..

    That is failing to boot, or the 2.6.32-rc8 kernel? No chance to capture
    the dmesg of the one failing to boot unfortunately..
