So yes, you can swap the motherboards out without issues.
Well, it boils down to what is technically possible and what is possible within the terms of the license agreement.
The OEM license agreement DOES state that software cannot be transferred from the hardware on which it was originally installed. A "transfer" is defined by Microsoft as moving the software to a machine with a different motherboard. In effect, this does limit your ability to perform a major upgrade of your machine and use the same copy of Windows.
This is one of the reasons why an OEM license is so much cheaper than a retail license; you get what you pay for. BTW, these terms are no different than the terms stated in previous Windows OEM licenses.
Now, if you were to swap out a motherboard, you would certainly be prompted to reactivate, and you might be able to reactivate online without issue. In fact, even if you had to call Microsoft, you might be able to get a reactivation code from them without issue. So technically, it's unlikely that Vista render itself useless after a motherboard swap. Still, those ARE the terms of the license agreement and consumers should be aware of them.
