powernow-k8 can of course be used for MP laptops/workstations/servers.

The problem of your "customized" machine is, that the BIOS does not recon the
CPUs and thus cannot expose the needed cpufreq info to the OS via the _PSS ACPI
function.

You could try to implement the _PSS function yourself and override your DSDT,
but that is not perfect (e.g. DSDT table changes on HW changes, e.g. exchanging
memory).
You could also patch powernow-k8.c and statically fill the needed values.
Best you complain to the vendor, anyway. CPUfreq won't work with this type of
CPUs on Windows, too.

There is nothing that can be done to enhance the kernel to support your
machine, this must be done in the BIOS or you go for a private patch which is
not worth it.
