Gnuk supports RSA keys up to 4096 bits. This require 1024 bytes of storage (p and q are 256 bytes, n is 512 bytes). The linker script should therefore reserve 1024 bytes per key instead of 512. In practice it's not an issue at all as all supported MCU have a page size bigger than 1024 bytes and Gnuk use one page per key.
