Doesn't that tend to happen now, every time ipf gets updated.
Or has someone managed to get the code to use ioctl requests
and versioning so that the new utils can load an old kernel?
(and coding for binary compatibility so that a new kernel
can be loaded with the old rules by the old utils.)

I can imagine :-)

I was thinking that ipf could load a 'pass all' ruleset from
the rc script 'as shipped'.  But once configured that would
no longer happen.
