By definition, the 2.5.x kernel tree is a development tree.
Network cards are cheap.  I would recommend buying a card supported
by a 2.4 Linux kernel and trying to reproduce the issue in that setup.
I don't think spending time trying to track down an interop bug with 
2.5 would be the most effective thing for us to do right now.
