I Googled "altera unique serial number" (yeah, I know, you are kicking yourself for not doing that ...)

Actually I did... with that search google gave me (and still gives me) a bunch of links for illegal quartus warez serial number cracks.... and a few links related to MAC addresses for people running linux on NIOS.

You are looking for the "Altera Unique Chip ID IP Core User Guide".

Thanks. I have to say it is very unhelpful that they plaster the acronym "IP" all over this. It's a hardware feature I'm looking for, not IP.

I started Quartus, made the IP Catalog visible,

An IP catalog is (and continues to be) the very last place I would look for documentation about a hardware feature.
If Altera is sticking documentation about their device's hardware properties under something titled "IP", then they are just completely bonkers.

I suspect that this IP core is not supported with the Cyclone III.

Thanks, but I don't really care about IP cores, I want to know if the device physically has die-unique fuses blown out at the foundry. It's a pretty clear-cut answer; they have to put it through a whole extra far-back-end step at UMC. Either they did or didn't do that.

A work-around would be to create a read-only register. The downside to that solution is that you need to re-synthesize for each device.

As explained earlier, that is not an option here. The product on which the Cyclone is deployed has no nonvolatile storage of any kind.
