BTW: while building I got a compile error: arch/i386/kernel/cpu/cpufreq/speedstep-smi.c: In function `speedstep_set_st= ate':arch/i386/kernel/cpu/cpufreq/speedstep-smi.c:183: error: `freqs' undec= lared (first use in this function) I worked around that to get it to build, but something needs fixing there, obviously.
