I have a long standing, not merged, patch from Ian Lance Taylor
(formerly
binutils maintainer) that lets the network stack work under Linux.  
The problem is the underlying conflict between RTEMS calls, header
files, etc.
and the native ones.

Personally, I would investigate either a CPU simulator or a virtual PC
environment like Plex86 or VMware.  I think the Cygnus/RedHat SID 
simulation environment includes some simulated network devices.

IMO it is better to work on a simulated CPU since that is closer
to the real thing.
