[CentOS] Opteron, Athlon/64, and disaster recovery

[Benjamin Smith]

Client is cash-poor, in particular, is really feeling the squeeze from the 
death of the dial-up industry. 

Saving $3,000 while still providing reasonable options for "worst case" can 
provide a lot of brownie points... in any event, I've done a fairly large 
number of hardware swaps between P3/P4/Athlon systems, and haven't had much 
trouble with it. When the next Opteron server comes in, after I've set it up, 
I'll test it out on an Athlon/64 system I can borrow for a bit and see what 
issues I run into.
