 Thanks for testing. Unfortunately, I don't know if there is much more
 that I can do to help you. However following information might be useful
 for solving the problem:
 
 - Did acpi_hp(4) work with previous FreeBSD versions? If it did, what is
   the exact working version?
 - verbose dmesg(8) output from working and non-working versions
