Hmm, not sure whether this is really fixed yet, could you try a kernel with latest ACPICA patches in (try to use Len's ACPI test tree, not sure what is the latest ACPICA in there it should at least be 20060608). If it does not work yet, please comment in the bug and I try to track it down. The max_freq is never reached because _PPC always returns 1. I couldn't identify what goes wrong inside there, this looks like a BIOS issue to me and HP eventually takes care (already updated to latest BIOS? -> better do that before starting anything else). Would be nice if you can add a comment there (including your machine model), this might help to get HP to have a look at it, they care about Linux compatibility...
