If for some reason gEDA doesn't allow to switch to another refdes letter inside the schematic (which would be sort of strange because of differing preferences in various countries) you'd have to make a new part, then set it's refdes letter to "X". "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 ...").
