Without hacking some extra boot options into xen I'm afraid you're not
going to have much luck -- we kinda assume the BIOS is at least
competent enough to generate a plausible e820 map. 

I guess Xen should work on a Pentium Pro, but I can't say I've ever
tried it. Early versions of those CPUs have some scary errata...
