Update: the card is working right now. I'll continue to monitor the situation and report back if it ceases to work again. What I just did was open up the laptop, disconnect the wifi card from its m.2 slot (leaving antennas connected - those connectors feel fragile), tape it into an empty part of the laptop case, and then boot the machine. Obviously, no iwl-related dmesg log contents for that boot, since the card wasn't detected. I then turned off the machine, reinserted the card into its m.2 slot, rebooted the machine, and - success!
