There shouldn't be that many non-kernel sunrpc users that require
privileged ports.

The exceptions I can think of are

* the 'mount' program, if you are using the legacy binary mount
interface. Use text mounts instead...
* rpc.statd might also use privileged ports when booting the
system when it needs to notify servers of the reboot. You can
set that port number using the '-o' option.

Others? Do any of the NIS services require it?
