Indeed, first-page-number is only read for the first book part, then
it is set for the following ones to
 previous-book-part-last-page-number + 1.

It is possible to accomplish what you are asking by changing the page
header formatting markup, as is demonstrated in the following example.
Do you think that using this hack is enough? or should I change the code
so that first-page-number should be read, when defined, for all book
parts? (I have no idea what side effect that would cause, except
confusing \label:s and tables of contents)
