(Someone please let me know if this is not correct)

I *think* you can go into kdb as root and type "stat" and the second  
line will tell you if you have a cpu capable of 64 bit operations.

You can build 64 bit libraries in 32 bit mode -- it depends upon your  
processor type.  kdb will tell you that.  Its probably somewhere in  
ODM as well.
