AFAIK, you cannot run 32bit guests on 64bit hosts and the HVM support also 
lacks in the stock CentOS version (which is a 3.0.3/3.1 mix). As I'm not 
using both I can only reflect what others say. The latest version in 5.2 
may also have some patches that Xen 3.2 has and thus works better.
You are also getting the xenstore and it's functionality and better 
networking scripts (the virtual network interface structure changed 
significantly) with it. There were a lot of improvements from 3.0.3/3.1 to 
3.2.

My experience to date with CentOS is it tends to run the

That specific package from xen.org runs really well, but you also have to 
add two or three patches.
