Suspend on ThinkPad L510 with `pm-suspend`

[Atemo-C]

Greetings. NixOS works on my ThinkPad L510 (albeit with difficulty when rebuilding the system due to having less than 2 GB of memory available), but suspending using the default systemctl suspend command simply does not work, and this is the case on any modern systemd-based Linux distributions on this hardware.

Currently, I have my own workaround in this module, and was wondering if the pm-suspend workaround in said module would be a good idea to implement here.

This could also be easily replicated for hibernation, but I have had no issue with that on my end.

Cheers.
