320623 seemed odd
and typing svn up gives 320659
and svn info indeed gives 317487 (2017-04-27) as the last changed
revision.

(am I misusing svn?)

Also, I thought that I specified powerpc64.

Indeed, the problem seems to be the loading of a kmod that does not get
updated until installworld. My fault (or some missing information in
the handbook).
