Only MSFT could answer that right now. There are a number of conflicting information on this and I would take it all with a grain of salt until it's all confirmed.
From reading the Vista NG many people there seem to be convinced that if your system dies, then your Vista OEM dies with it. Some say that certain components can be changed without anything required, while other components (MB, HDD?) will require you to call MS and get reactivation.
Of course MS reserves the final say whether you actually get reactivated or declined. I'm of the opinion that MSFT will act in good faith on this considering they're forcing this activation and new EULA on everyone and many people are not happy about it. There will, I'm sure, be a grace number of hardware changes that OEM licences fall under but who knows what that number is.
