Meanwhile I found out why - the modules are deprecated (on i386 also) and the code from speedstep-centrino has been merged into acpi-cpufreq. I reinstalled the system in 32bit mode and the issue still persists.
The reason behind this is that the ACPI tables (DSDT, but i suspend rather the SSDT) are broken, which is a fault from the BIOS vendor. It is possible to overwrite these tables during system bootup, but one has to fix/supply the tables first which seems not very easy.
