Is the non-realtime driver a standard network driver, i.e. do you get 
some new device which is configurable with ifconfig? Then it may not be 
impossible to port the driver to realtime space (assumed that it is Open 
Source).

RTnet uses a network driver model which is very similar to Linux. Our 
Ethernet drivers are all ported from standard Linux. Take a look at 
README.drvporting (rtnet/Documentation) to get an impression of what 
steps have to be performed.

Furthermore, as FDDI would be a new media type, some internal extensions 
of RTnet would probably be required - it's a bit difficult to say how 
much work this would cause, but it should be feasible (most parts of 
RTnet are already prepared for new media types).
