The AMD64 tree isn't building a bzImage in arch/x86_64/boot/ ,
and the top level vmlinuz doesn't seem to work with GRUB 
(or I'm passing the wrong arguments, I'm not sure).

Here's my grub boot line:
        kernel (hd0,0)/vmlinuz-2.6.15-xen-dom0 root=/dev/hda5 
        initrd (hd0,0)/initrd-2.6.15-xen-dom0

I get a GRUB error "Error 13: Invalid or unsupported executable
format" when I try to boot, though.
