I hope I can add something here, because I am experiencing the exact same Problem as Don describes. I'm running a PackardBell EasyNote MB89 featuring a Core 2 Duo, 4 GB of RAM, Intel Chipset (Santa Rosa), SATA HDD. My Machine even hangs at boot, absolutely doing nothing until i wiggle the touchpad. This is definately reproduceable, but I think it doesn't occur that often in X-Window-System, if X is off I can just wait a couple of seconds and there I go.
I compiled other kernels myself with tickless disabled and Ticks set to various values (250, 1000) which completely resolved my problem. If you want, I can get you some Output/logs/whatever because I'm fixed to using this kernel ATM (which doesn't really hurt because I use X and son't shut down my Notebook that often). Even though I don't know what exact kernel-version this problem brings (using another machine ATM from vacation) I can say that I existed since Opensuse 11.1 I guess, so maybe 2.6.30 and above.
Hope I can help --
Stefan
