Can you show the steps you took to recompile and install those? Not to
condescend, just bearing in mind that you said you were new to FreeBSD.

11.16.5.1 _OS dependencies
Some AML assumes the world consists of various Windows versions. You can
tell FreeBSD to claim it is any OS to see if this fixes problems you may
have. An easy way to override this is to set hw.acpi.osname="Windows
2001" in /boot/loader.conf or other similar strings you find in the ASL.

It may be worth trying setting hw.acpi.osname to "Linux", or to one of
the others mentioned in your ASL. You'll see a number of conditional
tests on 'OSYS' in there; I don't know just what they do, but it can't
hurt to experiment.
Try 'Windows 2001' also; there are some tests in the EmbeddedControl
section mentioning an RFLG and VIST .. clearly the latter refers to
Vista, but Windows 2001 zeroes RFLG, otherwise set. (just guessing!)
While not ruling out a possible new bug in ACPICA, this is more likely
problem/s with your ASL than with FreeBSD as such. Keep an eye out for
a BIOS update; if you do contact HP they might at least be aware that
there's a problem, especially if you mention that wrong PNP0C14 string,
the only one I spotted having lower-case letters.
cheers, Ian
