Up to Tiger, any version of Mac OS X runs on hardware as old as a  
PowerMac 7600. The only reason you can't just pop in the Installer  
DVD is, Apple has put consciously a few barriers into place to  
prohibit running Tiger on non-FireWire hardware.

Once you work around these barriers, things run slowly but smoothly.  
Unix's hardware abstractions easily manage all the details.

So, the idea, Apple would clean out just a single line of code as  
soon as some type of hardware is no longer supported is ... without  
evidence. In fact, they will add code here and there to make sure the  
software requirements match the advertised ones. More chances for  
bugs instead of less.

No. But with the release of Leopard a lot of people will either have  
to toss their older Mac to the trash, have to live with a mixed  
Leopard/Tiger environment, have to stick with all Tiger or have to  
hack the installer DVD. Just because Apple advertises a randomly  
choosen limit of 867 MHz.
