Webcam, fair enough.
These are only not a problem because they don't do anything at all, because of some clever tidying up maybe 12? years ago when there were still a few APM BIOS laptops made. I had one between ~2003 and 2019.
ACPI precludes APM, and amd64 mode requires ACPI.
APM functions are now just emulated with corresponding ACPI functions, eg apm -z will suspend exactly as acpiconf -s3 will, apm
derives battery info and state from where acpiconf -i0 does.
If not convinced, see
% less `which zzz`
which shows that presence of sysctl machdep.apm_suspend_delay
indicates real APM support, despite what
'apm -e enable' suggests.
Were these trying to solve some problem?
