The version may be passed as an command-line argument

Two things:
1) ioreg is accessible even by unprivileged user
2) output of "ioreg -lw0" contains complete system information. So when someone asks we for help with his system it's much easier to ask them to send output of "ioreg -lw0" then explaining how to install different diagnostic tools. So having to be able to decode SMBIOS from "ioreg -lw0" would be very useful
