I updated that snippet a few months back because the instructions are different on Qubes 4.0.x and 4.1.x. Did you get those results when running the new Qubes 4.1.x instructions?
As far as suspend, at least so far I haven’t run into your issue at least as far as I can tell, although I don’t often suspend this laptop (it tends to live on my desk). I did an upgrade from Qubes 4.0.x to an early version of 4.1 and then have been doing the standard dom0 updates since then, although I haven’t yet run the very latest update.
