Which kernel are you using? I think all recent kernels have also dropped support for non-PAE PV operation, so you would probably have to go back to a kernel of that era to get non-PAE support. But I'm not really sure what relevance PAE has to what you really want to test. Limited memory is a side-effect of non-PAE operation, but if that's what you're concerned about you can easily limit memory size (either by telling Xen to only use 4G of the system's memory, or by limiting dom0 to 4G).
