Not quite, because AFAIU, it is ACPI's philosophy that suspend happens
transparently in the middle of a userspace script, which also handles
resuming. So I configured Fn-F4 and the lid closure to run
/etc/acpi/actions/suspend_and_resume.sh, which I enclose with this mail.

Is it the ACPI way, or am I just wrongly struggling to reproduce the
APM way with ACPI?
