IIUC this patch is by Christophe Dumez and can be found at http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-maverick.git;a=commitdiff;h=23120eb5a Unfortunately, at https://bugzilla.kernel.org/show_bug.cgi?id=7463 we see: Comment #13 From Andrew Morton 2007-10-18 13:44:59 I asked davej about this and he said: The only safe way to use scaling on 'dothan' cores is with ACPI. We just have no way to tell which of the four sets of voltages is in use. People keep proposing patches to hardcode a set of tables for them which "works for them", but could do *anything* on someone elses system. Even if we added it as a CONFIG option, I'm worried that people will turn it on not understanding the consequences and either plague us with crappy bug reports of flaky kernels (or worse). (And you guarantee some distros will turn it on to "make hardware 'just work'") All-round crappy situation really, we're between a rock and a hard place, and ACPI is the best hope we've got.
