"QX" won't work, usually. I bet one can fix that right in gEDA, maybe someone can shed some light.

The refedes renaming is in spice-sdb: it has heuristics that attempt to fix the prefix for SPICE (see sections 4.7 and 4.8 of http://www.brorson.com/gEDA/SPICE/x150.html). I personally have had more trouble with these than success, so Stuart kindly added the --nomunge option to turn the renaming off ("gnetlist -g spice-sdb --nomunge ...").
