I don't think it makes sense to put it under hw.sysid.smbios.  I like the idea
of hw.sysid, but then to have an additional node under smbios seems like it
would make it harder to use this information in an MD way, you would have to
know the leaf nodes for all the different systems.

For example, on prep, we have:

PrintableModel = IBM Model 7024E20 (c0ED)        
Serial = IBM70249451371
FirmwareSupplier = IBMFirmware

I can see how the serial number might be useful as a unique ID for this machine.
