It's explained in acpi(4); you can specify the boot loader variable
debug.acpi.disabled as a space-separated list of keywords (or a keyword)
from below:
  ec sysresource
  cpu cpu_cst cpu_pst
  video button 
  timer hpet
  acad cmbat lid thermal
  bus children all

  pci pcib pci_link
  quirks isa

- all, bus, or children disable almost everything, so try them at last.
- cpu_cst and cpu_pst are subdrivers of acpi_cpu, so specifying ``cpu''
  disables both of them.
- if it's not a laptop PC, you most likely don't need to bother with
  acad, cmbat, or lid
- if you experience occasional lock-up and either ACPI or HPET is chosen
  as the cputimer (sysctl kern.cputimer.name), try disabling timer and/or
- pci, pcib, and pci_link are disabled by default; you need to explicitly
   specify them in another variable named ``debug.acpi.enabled'' to use
- although listed in acpi(4), I couldn't find where quirks or isa are
  checked against.
