Agree.  qemu should simply autogenerate the entries (where it can).
i.e. basically port seabios smbios_init_type_17 function to qemu, then
hook the result into the smbios_entries array.  The code to do that is
in smbios_entry_add().  You probably want to factor that out ino a small
helper function which is then called by both smbios_entry_add() and the
type17 init function.
