Let's relax with the hysterics.
The mechanic is crappy and lazy but not totally wrong. Tweaking that tension to get the light off is a pain and he doesn't want to do it again after the belt relaxes. The fact is that the newer belts don't relax much at all and after 100 miles the tension will be stable.
You need a "Kempf" tool, a 10mm socket, a 17mm wrench and about a half hour and you can tension that thing yourself. You'll feel a good deal of satisfaction when you're done and when you tell that mechanic you did it yourself and you won't be back, ever.

It could also be like an 85 I've got here. The tension is correct but on the tensioner arm, the metal contact is busted so it has lost ground, keeping the circuit open. The repair is to pull the entire front off and putting a new tensioner arm on it.
Have someone that knows what he is looking at, if that is the case, then you know what your choices are.

If the light doesn't go off with the tension set tight, or a bit high, then you'll know something is wrong.

Also, the harness might be messed up. An easy check is to pull the wire off the cover (behind the dipstick) and ground that. Run the car for 3-5 minutes. If the light does not come on, that will tell you to look behind the front cover.

I would repeat the test a few times, at different ground points. Sometimes getting a good ground can be tough with engine vibration etc.
I stick a piece of wire in the harness connector and use alligator clips holding it to ground. Use a multimeter to ensure you have a constant ground and have zero resistance in the connection. Start up and repeat.

It will tell us where a fault is. May be multiple ones.
What it won't tell us is if the belt is actually tensioned properly, but narrows down possible issues.
I would still have someone who KNOWS 928's take a look at the tension. If the mechanic was using a proper tension tool, then you should be good to go.

There is a break in the wire someplace in the harness. Take a look at the wire you can see, and check for breaks/chafes on it.
You should go to the jump post and take a look at the 14 pin connector and ensure that it is corrosion free and in good shape. Tearing in to the harness its self is something you might need to do to find the break.
Do you have the Work Shop Manuals (WSM's)? If not, and you plan on working on it yourself, please get a copy on CD or search here for links. They will save you a lot of time and grief.
