I'm surprised you're having trouble with 64MB -- xend is pretty fat, but
its not that fat! Some of the memory dom0 get's booted with
actually gets returned to Xen, so you'll probably find the memory
usage reported by 'xm list' is a few MB lower than the amount you
started it with. 

Are you sure you're not starting some other application in your
rc scripts that is consuming a lot of memory? Perhaps configure a swapfile...
