I was wondering why gkrellm was reporting such high CPU temps (51C) on the Atom N455 that was mostly idling (for comparison, my desktop Phenom II 3.4Ghz is running at 38C in "ondemand" mode).

Running 'powertop' on "Linux meegolem 2.6.37-7.28 #1 SMP PREEMPT Tue Feb 22 03:55:51 UTC 2011 i686 i686 i386 GNU/Linux" I notice the following: "Suggestion: Enable the CONFIG_INOTIFY kernel configuration option. This option allows programs to wait for changes in files and directories instead of having to poll for these changes" Is that a valid suggestion
The suggestion is extremely valid. Without it programs will default to polling because there is no other method to monitor files and folders.

You're not running MeeGo now, are you? The kernel version string suggests you run something else :P
The reason for asking is that this is a lot of unnecessary interrupt activity on a mostly idle system: 28.3% ( 59.9) [i915]<interrupt>
graphics interrupts. Seems like something is requesting interrupts from the gpu.
apart from that, the suggestion was recently changed to ask for CONFIG_INOTIFY_USER instead of CONFIG_INOTIFY, since that option no longer exists in the kernel config. Check if your kernel has this option enabled instead. This will hopefully make it into a new release soon.
