I know only one open source GIS software which creates PDF files with 
layers. It
is SkyJUMP by Larry Becker and I have added a sample to Geoserver feature
suggestion some time ago
http://jira.codehaus.org/browse/GEOS-3640

The jira issue has has a sample image as an attachment
http://jira.codehaus.org/secure/attachment/45741/SkyJUMP.pdf

and a comment that layers are selectable with Acrobat Reader but not with 
all
readers. I know that SkyJUMP is makind PDF with iText and layers are 
raster
layers. The image is fine and worth having a look.
