Not sure what's the 15/..., but here's the content: % cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 9 model name : Intel(R) Pentium(R) M processor 1600MHz stepping : 5 cpu MHz : 598.132 cache size : 1024 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr mce cx8 sep mtrr pge mca cmov pat clflush dts acpi mmx fxsr sse sse2 tm pbe est tm2 bogomips : 1197.24
BTW, speedstep worked fine on my laptop with 2.6.12-rc5-git5 and earlier.

Well, is there some way of doing a bisection over these changes? As far as I know, the problem probably affects all Dell D600 owners, probably others.
