This sounds like a good solution to me. I think it's definitely more appropriate than simply bumping up the size of xen_e820_map, especially considering the fact that it's theoretically possible for the e820 map generated by the hypercall to grow too large, even on a non-EFI machine, where my change would have no effect.
