expanding custom keywords in dump

I’m trying to automate the real-time importing (mirroring) of the
FreeBSD SVN tree into a Perforce tree. This is not for FreeBSD
development but to allow integration of two projects, both based on
FreeBSD (and leaving p4 is not an option :-( ).
Perforce have a tool that takes a SVN dump and converts it into
perforce transactions in a very 1:1 way (p4import-svn).

Unfortunately the one thing that fails is that custom keywords are not
expanded. This doesn’t seem much but in the merged project there is no
way to see what revision of file was imported from the FreeBSD
repository, as the “$FreeBSD$” keyword is left unexpanded on export.
This also means that files that are moved across to Perforce will
always have diffs with files taken from the DVD images as they have
the keyword expanded. One project started with a DVD image so the
large project i’m merging with has a lot of freeBSD files taken from
that DVD, and thus there are a lot of false merge conflicts.

Is there any way that the subversion dump routine can be configured to
allow expansion of these keywords? In this usage, the dump is
effectively playing the part of the client. Having it expand the
keywords would allow the expanded version to be imported into Perforce
which would then contain files that would match what is exported on
the DVDs.
Would this even be a useful thing for exporting the a project repo to
another SVN based repo so that such keywords would be “frozen” in place?
