It's not a module but a part of GRUB kernel, just compiled separately
because it's the only part of kernel that is not compressed. On
runtime it's loaded at 0x8200 and main GRUB kernel resides at 0x9000,
so decompressor can't be more that 0xe00. So far this was never a
problem except this case which turned out to be alignment issue and
it's good that we catched it since it wasted a lot of place in core
since this part is not compressed
