64bit dev_t's are going to cause some real problems. I would suggest you try passing a 64bit dev_t over NFS - especially to non unix clients before you do this.
If you go to a 64bit dev_t you will have to do hackish horrors for NFS support even Linux to Linux. Stay with a 32bit dev_t, supporting more device files than we can create 1 a second within our epoch is crazy
