You could set NR_OPEN to 1024 and set the rlim[RLIMIT_NOFILE] to 256 for compatibility.. Programs that want to use the larger fd_set can then increase the rlimit themselves.
I want to experiment with this myself in the near future; we have a machine with a dedicated squid wwwcache running and very soon 256 fds will not be enough.
