My laptop (sony vaio pcg-v505bx) has a Pentium 4 M, but not Centrino (which name is... Pentium 4 M too), afaik it's capable to support speedsted, (enhanced or not?).

My processor also supports for speedstep and dmesg looks like: #dmesg|grep CPU CPU: Mobile Intel(R) Pentium(R) 4 CPU 2.30GHz (2224.01-MHz 686-class CPU) in the est.c code i found out the followig: ....... err = kernel_sysctlbyname(curthread, "hw.model", hwmodel, &modellen, NULL, 0, NULL); ....... if (strncmp(hwmodel, "Intel(R) Pentium(R) M processor", 31) but my sysctl hw.model returns hw.model: Mobile Intel(R) Pentium(R) 4 CPU 2.30GHz The same as in dmesg. Changing the code to find a substring Mobile in hw.model delivers system stuck at the module load time. -- Best regads, Anton Nikiforov [-- Attachment #2 --] 0 *H 01 0 + 0 *H 00: 0 *H 0b1 0 UZA1%0#U Thawte Consulting (Pty) Ltd.1,0*U#Thawte Personal Freemail Issuing CA0 040305211228Z 050305211228Z0D1 0 UThawte Freemail Member1!0 *H anton@nikiforov.ru0"0 *H 0 >qNv`"9 &:Bf*Ku;,h&Pt5 -BCIZ(\X"{)Ûf<WWPUg |1X{-B֟3 j@rM@чj I'r ֨ i&ƨMٕY~O9{gRᤳfJ b+e?sxJd/kaVErzG)Kao_B\E![u]ż_{ސץ /0-0 U 0anton@nikiforov.ru0 U 0 0 *H p1zaGK,U-r%#&CTJ`Q'Xx:GQ.
