I've used subcircuits with parameters before without issue, but I'm not
certain why I can't now.

I've attached my schematic, but the key attributes are:
refdes=X1
device=PFWR
file=fwr.inc
model=gain=2

(I've tried other variations, but
http://www-mdp.eng.cam.ac.uk/web/CD/engapps/geda/geda-doc/spice-sdb/netlist.htmlsays:

"Active components should call out this name in the "device" attribute to
associate the component with its particular spice model or subcircuit."

fwr.inc contains a simple example:
.SUBCKT PFWR In Out gain=1
B1 Out 0 V=abs(V(in)) * {gain}
.ENDS PFWR

The netlister (spice-sdb) generates (with comments removed)
.SUBCKT PFWR In Out gain=1
B1 Out 0 V=abs(V(in)) * {gain}
.ENDS PFWR

V1 in 0 SIN 0 5 100
X1 in out unknown
.end

The netlister output doesn't really look confused. If I instead of doing it
like that web page suggests, and instead make the device=SUBCKT,
model-name=PFWR, model=gain=2, it does at least get the correct subcircuit
label:
    X1 in out PFWR
but it still doesn't append the subcircuit parameters.

1) What's the correct attribute set to get the netlister to append
subcircuit parameters.
2) Is the netlister broken or is my example broken?

Nate
