FYI rtems 4.9 branch has shared interrupt support on the
i386.  It was not much code and I added it.  I would recommend
extracting the patch from CVS if you want it on a release
4.9.x unless you are willing to work on the 4.9 branch
from CVS.

FWIW the network-demos have a networkconfig-qemu.h
which has the network configuration required now.  You
will have to define USE_LIBBSDPORT. 

I use this driver all the time.
