#  It is strongly recommended to use HZ=1000 or 2000 with DEVICE_POLLING
#  to achieve smoother behaviour.
#  Additionally, you can enable/disable polling at runtime with the
#  sysctl variable kern.polling.enable (defaults off), and select
#  the CPU fraction reserved to userland with the sysctl variable
#  kern.polling.user_frac (default 50, range 0..100).
#
#  Not all device drivers support this mode of operation at the time of
#  this writing.  See polling(4) for more details.

#  defined when it is built).
#
#  ACPI_MAX_THREADS sets the number of task threads started.
#
#  ACPI_NO_SEMAPHORES makes the AcpiOs*Semaphore routines a no-op.
#
#  ACPICA_PEDANTIC enables strict checking of AML.  Our default is to

#  - IBM ThinkPad T42 (23735TU) - When (ACPI was disabled and) apm was
#  - enabled and Fn+F4 key sequence was pressed in order to suspend, in X
#  - (Xorg 6.7.0), system seemingly froze.  Trackpad was not responding, but
#  - TrackPoint was; pressing any 2 sets of buttons -- 3-button cluster or
#  - 2-button cluster -- did not respond.
#  -
#  - Further, Ctrl+Alt+Backspace did not kill X; VT-switching did not work
#  - either.  If it makes any difference, hw.syscons.sc_no_suspend_vtswitch=1
#  - was in effect.
#  -
#  - There is no problem in suspend/resume, in X or console, when time period
#  - in between the cycle was about <10 minutes.

#  Power management support (see NOTES for more options)
#  - In 5.4, enabling apm dev & setting acpi in loader.conf allowed acpi to be
#  - loaded in favor of apm.  As of 5-stable-2005.10.04.18.00.43, this has
#  - changed such that, enabling apm loads apm w/ loader.conf acpi instruction
#  - having no effect.  Apparently.
