I use the split-up symbols for most logic parts.

Last year I posted a utility that reads a gschem logic symbol file
with embedded power connections and outputs a new symbol file
without the embedded power connections and a new symbol file with
only the power pins.

The script worked on the 74xx series symbols that come with gschem.
The script is at http://www.luciani.org/geda/util/util-index.html
