I just installed SuSE11 with kernel 2.6.25.18.0.2-xen PAE on a 16 core 64GB equipped Caneland machine. 
After booting dom0, top shows that roughly 50GB are missing.

Where did all the memory go?
This is more of a xen-users question, but what you're seeing is the memory allocated to the privileged guest -- "xm info | grep mem" will show you the full extent of the memory available to dom0 and any domU's you might have.
