is the regulator on the PCm accessible? When it goes...just rip it out or bypass it and go with a REAL alternator!?
Regulators usually need a few volts more than what they are regulating to. (12V regulator needs 14-15volts input). So, if you want to hack your 'real' alt and put in a higher regulator, then the computers' regulator would still regulate and it should still work!
Replacing the generator part isn't the issue, it's when the PCM regulator toasts...

The PCM provides as varying ground to the field circuit of the alt. to control voltage output. I assume that the PCM looks for varying output as it controls the ground. If it doesn't see the voltage vary, it'll turn on the light. I'm not adverse to ripping the thing out and going with a Delco one-wire, but then, if some emissions thing went wrong, I'd have no warning of it. At $59 a pop, I can afford to rebuild the alt every 185,000 miles or so.
