For old APM stuff yes you can get apm messages. X has some bits for it.
Modern systems have all switched to ACPI and most current distributions
(non enterprise anyway as enterprise lags a little) use ACPI. The ACPI
layer has code paths that allow scripts to execute on ACPI events.
Naturally enough that can including poking X11.

Coming back from ACPI S3 is still a research topic alas
