Moving !LDR should work fine, but if you're getting an error about
missing params then you still haven't wiped the old Amstrad LDR. ISTR
that PBL will do remapping in the NAND using the area that ends up as
mtd5 (last 192k of NAND), so it might be worth trying to erase that area
of NAND and see if that causes your !LDR image to be seen instead?
