for me it looks like, that either already grub_relocator_alloc_chunk_addr or at latest grub_relocator_prepare_relocs should bail out with an error, if the memory range of the VGA memory (0xa0000 ++) is covered. What I don't know, respectively didn't found in the code, how and where this information about this VGA text memory area is excluded/reserved from the allocator/reallocator. Maybe you can give me a hint ?
