[wplug-internet] Linode upgrades

OK, so I tried an experiment, and had one of my personal Linodes 
migrated to the "nextgen" hardware.

And, after that migration ... the Linode would not boot.  Because that 
Linode was using a 32-bit CentOS kernel, and the new hardware won't boot 
a 32-bit CentOS kernel...  Support recommended that I boot using a 
64-bit kernel, and that worked, but of course the whole rest of the 
system was 32-bit...  "yum update" was somewhat confused....

So, they migrated me back to the L5520's, and that system is running 
again (though still with the extra RAM boost).  As the WPLUG server is 
using a 32-bit kernel, it looks like we'll eventually have to deal with 
that.  From what I've been able to tell, there's no way to "convert" a 
32-bit CentOS installation to 64-bit "in-place" - looks like it's a 
"backup all user data, do a fresh CentOS install, and restore user data" 
situation...
