Rest assured the same cards will work in both 68K Macs and (some) 
PowerMacs.  I bought two used Apple Twisted Pair LC-III/PDS cards about a 
year ago.  They are built using the SONIC-T chip which I had mistakenly 
assumed would work with the NetBSD Sonic driver at the time.  
Unfortunately they didn't, but with the help of Allen Briggs and Denny 
Gentry we got them up and running last summer. Now one of them sits in my 
68K Mac (Performa-550) which runs NetBSD and the other sits in my PPC Mac 
(Performa-5320).  They happily chat to each other and to my PC laptop.

For what it's worth, the Performa-5320 is built using a motherboard 
similar to the Performa-6300 which is (I think) a slightly updated 
version of the Performa-6200.  You're probably right about the Comm Slot 
(I and II) cards, but the LC-III/PDS slots seem to be the same from my 
experience.
