I'm pretty sure that Dell's Active Power Controller would supersede what the intel-pstate driver/governor is trying to do as well. I doubt you will have enough control over the box to do meaningful tests until you can get the BIOS power setting changed to "OS Control". speedstep and p4-clockmod are both ancient. But it is all moot if the BIOS won't let the OS manage the CPU. It is possible your distribution is a bit too stripped down. You might want to build and install your own kernel so you can make sure all the sensible options are in it. But it is also possible acpi-cpufreq is built in so you don't see it as a module, and it is not possible to activate it due to the Active Power Controller getting in the way. Meanwhile, can you rmmod intel-pstate?
