*** Bug 12468 has been marked as a duplicate of this bug. ***
I have verified that the three patches above make a cpufreq-enabled upstream kernel able to resume again on my T61. I cherry-picked them from Ingo's tree here: http://git.kernel.org/?p=linux/kernel/git/tip/linux-2.6-tip.git;a=commitdiff;h=31ad9081200c06ccc350625d41d1f8b2d1cef29f http://git.kernel.org/?p=linux/kernel/git/tip/linux-2.6-tip.git;a=commitdiff;h=8ccad40df8d314f786fdb06bdbedd4f43f3257cd http://git.kernel.org/?p=linux/kernel/git/tip/linux-2.6-tip.git;a=commitdiff;h=72859081851af2bda04117ca3d64206ffa199e5e (follow the "raw" link to get the text patch) While these were necessary, they were not sufficient, rc2 requires also a USB patch for bug 12422)
