We would definitely prefer the firmware solution. Quirking devices in
the driver would force everyone to subscribe to the less aggressive
power savings even if they're not affected.

How do they offer their firmware update? I think it's common for vendors
to provide some kind of bootable USB image that does the update if they
don't provide a standalone firmware binary or other tooling.
