  Szerintem (még) nem. Legalábbis itt azt írják:

  ,,Linux Torvalds has now integrated the one line patch to fix frequency reporting into the 2.6.34 Linux kernel main development branch.
  Several tests with a release candidate of Fedora 13 and various kernels that are based on Linux kernel 2.6.33.2-57.fc13.x86_64, which comes with the distribution by default, demonstrate the effects of the problem as well as those of the kernel patches. To compile Linux 2.6.25 with a maximum of twelve processes ("make -j 12 bzImage") in standard configuration ("make defconfig") using the "kcbench" bench mark, a test system with Phenom II X6 1090T required approximately 75 seconds. Compilation was about 20 seconds faster after Cool'n'Quiet was disabled via the BIOS set-up or by stopping cpuspeed. However, a kernel self-compiled with the aforementioned patch that only modifies one line required 59 seconds with cpuspeed enabled – that's four seconds more. On the other hand, with a kernel that included all six changes in the patch series created for 2.6.34 and cpuspeed enabled, compilation only took about 52.5 seconds. (thl)"

  Azért írtam, hogy még, mert tervbe van véve a patch stabil kernelágakba integrálása.
