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 lates= t 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 i= t 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...
