well, the upside would be that since most testing of Linux kernels is 
done on _old_ hardware (people tend to risk their old hw first ;-), we'd 
get faster convergence of the codebase, even though we have the risk of 
erratas (known and unknown ones alike). Code that artificially limits 
its utility is almost always slow to stabilize.
