I've put out pfiv1.5.tar.Z which contains fixes for retaining all
SoSwitch children and setting the active child. You can find it
in sgigate.sgi.com:/pub/Performer/src.

SoSwitch children were being loaded...... but only with Performer
2.0. To properly get a snapshot of inherited graphics state in
Inventor, SoSeparators need to be inserted between the SoSwitch and
every *inactive* child to prevent graphics state from leaking out.
This generates a SEGV inside Inventor when the traversal continues,
but seemingly only with Performer 1.2????. This new version of the
loader moderates the aggressiveness of the workaround.

rgds,
