Speedstep itself works rather fine, but I wonder about the available scaling frequencies: cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies gives only "668000 692000" ? ...and this is also what speedstep does - it switches between these two frequencies, 96% and 100% speed. Isn't this absolutely nonsense? Only 4% speed difference !? I now have fixed the bios' DSDT and built my own one in the kernel - no change. Furthermore I cannot find the numbers 668000, 692000, 668 and 692, neither in decimal, nor in hex in the decompiled dsdt. On the other hand my dsdt contains two entries in the _PSS section, one for 3059MHz (100%) and one for 1596MHz (~50%) - but those two frequencies appear nowhere in /proc or /sys/devices/... !? what goes wrong here ? Is speedstep independend from ACPI ?
