now that the FX are all in 2.2 gamma (right?)

wrong. Unless rendering directly to jpg, nearly all renderers will output as linear. Especially when output is exr. There aren't any extra steps to bring raw renders into nuke.

Why not use the name attribute to split the geometry into multiple mesh prims rather than use geometry subsets? The name sop can create names from existing groups. I've found geometry subsets sometimes have funky behavior with materials bleeding from one subset onto another.

This is a known limitation of several renderers, including renderman. It should work fine in mantra though.
