You have to enter in both CD-Keys. From the Upgrade CD, and the original Previous OS CD. (So in my dads case -- the Win95 CD-Key, and the Win98se Upgrade CD-Key)
That's the way M$ verifies you actually have the previous OS to which you are upgrading. Otherwise everyone could go out and just purchase the upgrades for $100 instead of full versions for $300, and M$ would be loosing some serious money.
That's also how their able to mark the price down considerably, since you already own one, just upgrading to a newer one..they're able to keep things a bit cheaper.

Well, in your case.. you can still get CD-Keys from other methods
I don't think it really matters which Key you use. It just wants to verify an old key with a new key.
But if you don't want to do that.. it's pretty much as you put it. You're screwed...and you might just want to go drop another $300 on a Full Version Cd. Or if you can find an OEM retailer, might be able to get it cheaper.
