For good measures, and luck, Apple published the OS-X 10.9.2 update lately. Since I was installing the new machine, I did the update right away, no backups done.
A simple manual edit (vi is my friend) changed a line in
/Extra/smbios.plist
to
<string>MacPro6,1</string>
and resulted in the fact that "about this Mac" => "more info..." shows a black trash can.
Actually, I am happy with a result of this nature, although I still appreciate the option to add more hardware to my trash can.
