I can't help thinking that if we wish to provide metadata to guest OS
like system model, serial number, etc, then we'd be better off using
explicit named flags (or QEMU config file settings once that exists)

  -system-serial 2141241521  -system-model "Some Virtual Machine"

and have QEMU generate the neccessary SMBIOS data, or other equivalent 
data tables to suit the non-PC based machine types for which SMBIOS
is not relevant.
