Telnetting to the machine reveals a telnet daemon that claims to be BusyBox 
(although I have no idea what the username and password are, the ones for 
the web interface don't work) so its definatly GPL software on the thing. 
As for the other stuff, I checked the manuals and CD and there is no sign 
of the source code or references to it that I can see.
