Peter Kaiser in Germany has done some chip designs using gEDA.  Here's
the website he put up recording some of his tips, including some
symbols for instantiating devices:

You might try contacting him in person if you have questions.  His
e-mail addr is on his website.

John Doty has also done mixed-signal designs using gEDA.  He has
published papers on his work, and has written an interesting gnetlist
back-end, all of which he has posted on his website.  I didn't see any
schematic symbols on his website, but here's a link:

John is very active on the e-mail list, so I expect that he'll turn up
to provide more info to you soon.

Cheers,

Stuart
