If I remember correctly there is no limit per device instance, but
during bootstrap the dictionary size is limited to 256k:
kernel/bootstrap.c:#define DICTIONARY_SIZE (256*1024) /* 256k for the dictionary */
and I think that value applies for the ports, too.
It's just an arbitrary numbers, we chose it a couple of years ago
when 256k was the usual size of system flash roms, so the resulting
openbios would always fit in a such a small chip with LinuxBIOS and
a compressed OpenBIOS payload.
