the Power6 and Power7 have the altvec and most of the rest of the PPC 
extensions.   when you compile for the power, if you are using gcc, you 
generally specify ppc as the architecture.  With IBM's XLC, of course, 
you specify Power 4 or 5 or 6 or 7.  Power 5 and later have extensive 
virtualization support native in the hardware, enabling LPAR 
partitioning of servers.

of course, this has nothing to do with centos, as far as I know, RH gave 
up supporting Power, and Sooshay was the official IBM distribution.   
with Novell imploding, I'm not sure what happened with Suse.
