Unfortunately I don't think you can. dumpon(8) says you can set a loader variable, but this is just an outdated manpage and that facility went away in 2002 (probably something to do with GEOM). However, DDB traces should be sufficient. Since you can reproduce this easily, please also turn on INVARIANTS, INVARIANT_SUPPORT, and WITNESS.
