I use a vmlinux as dom0, but it's a stripped vmlinux. A vmlinux with
full debug symbols is 55MB here, which probably explains this problem.

Could you see how easy it would be to catch this problem at runtime and
have a nice panic? Checking dom0_len in __start_xen() would probably do
the trick, maybe something like:
        if (dom0_start + dom0_len > (32<<20))
                panic("dom0 is too big");
