Try "model-name=PFWR gain=2" on the X1 symbol.

It's the only way I've found to force parameters onto the X line.  

There's actually a patch on launchpad that will make it easier to do
that.  https://bugs.launchpad.net/geda/+bug/698736 patches the
netlister so that the .subckt can get parameters when you do the
lower-level schematic with the SPICE-SUBCKT-LL symbol (I have found no
way to make it do so yet without the patch).  But it does NOT patch
anything to make the X line come out with the parameters unless you put them
into "model-name".
