I decided to revert the HP bios back to F.06, and now - to my surprise, on boot, I get an extra SSDT! (The CpuPm one).

Still, linux doesn't load either speedstep-centrino, or acpi-speedstep. I'll poke some more, but it looks promising. I wounder why the BIOS F.08 doesn't have the CpuPm SSDT? It appeared to flash correctly when I first installed it. Perhaps even booting windows (to downgrade to F.06) had some effect on the bios to bring back the SSDT? Perhaps it is only in the F.06. Does anyone have any contacts with HP who might shed any light on this?
