9e760f2578 acpi_hp.c:
- sysctl dev.acpi_hp.0.verbose to toggle debug output
- A modification so this can deal with different array lengths
  when reading the CMI BIOS - now it works ok on HP Compaq nx7300
  as well.
- Change behaviour to query only max_instance-1 CMI BIOS instances,
  because all HPs seen so far are broken in that respect
  (or there is a fundamental misunderstanding on my side, possible
  as well). This way a disturbing ACPI Error Field exceeds Buffer
  message is avoided.
- New bit to set on dev.acpi_hp.0.cmi_detail (0x8) to
  also query the highest guid instance of CMI bios

acpi_hp.4:
- Document dev.acpi_hp.0.verbose sysctl in man page
- Document new bit for dev.acpi_hp.0.cmi_detail
- Add a section to manpage about hardware that has been reported
  to work ok
