I have never read about "a spoiler flap in a speedbrake
configuration"
in any textbook. Anyone else?

You might want to look at the recorded parameters for the DFDR on your
747-400.

Sorry, but they don't let me bring home a DFDR. Exactly where would I
find a
reference to "a spoiler flap in a speedbrake configuration," and in what
context?

Look it up in CFR14, it is a required data element for digital flight data
recorders.
