Good!

See:

But now I get crash when init is started..

Starting udev: BUG: unable to handle kernel paging request at c1106840
IP: [<c04045ef>] get_phys_to_machine+0x24/0x29
*pdpt = 000000005fa7a001 Thread overran stack, or stack corrupted

Try again. I don't know if I specifically fixed this one, but I noticed that it wasn't reserving the 32-bit Xen pagetables, so it might have tried to reallocate them for the swiotlb buffer...
