Yes.
It include dissectors for LAPB and X.25 PLP, and for the low-level  
Frame Relay protocol, and you can add more dissectors.  (If you add  
them, you have to make the source code to the dissectors available to  
anybody who gets a copy of those dissectors, and must allow them to  
give the source code away to anybody they want to, without  
restrictions.  Probably the best thing to do is to contribute the  
dissectors to the Wireshark code base, which means we can update them  
if any dissector programming interfaces change.)
The only tricky part would be if you used Wireshark to do the  
capturing.  Whether it can capture traffic on a particular network  
type depends on whether the libpcap/WinPcap library can capture on  
that network type, and that, in turn, depends on the platform on which  
you're running, and the drivers for the network adapters.
If you don't use Wireshark, you would have to write the captured data  
to a file in a format that Wireshark can read; you can add new file  
formats to Wireshark if necessary (the same rules about the source  
code apply).
You'll probably have further questions in response to my message; if  
they involve making modifications to Wireshark, you might want to ask  
them on the wireshark-dev@xxxxxxxxxxxxx list.
