The pfGeoSet list is internal/private to the pfString class and unaccessible.
As a way to work around this limitation, you could try associating
a pre and post draw callback to your pfText node that would use a
pfSprite to force a billboard effect. Something like:

static int
preDrawCB( pfTraverser* trav, void* data )
{
   sprite->begin();
   sprite->position(0.0f,0.0f,0.0f);
   return PFTRAV_CONT;
}

static int
postDrawCB( pfTraverser* trav, void* data )
{
   sprite->end();
   return PFTRAV_CONT;
}

Check the man page on pfSprite. It's a nice feature added to libpr for
Performer 2.0.
