I would strongly recommend not spending a huge amount of time on the ml310.  The University program board is dirt cheap for universities, very well supported under Linux, using either secretlab.ca or git.xilinx.com and you won't spend your time getting PCI to place and route correctly, followed by figuring out how to get Linux to talk to it nicely.

If your lab can afford a bee2, then you should be able to afford one (or better yet, several) xupv2p's to go with it.

No problem.

Much appreciated; thank you!

Cool platform.  Yes, you should have much better luck with the EMAC
core.  The driver needs some work to be acceptable for mainline, but
it should be functional.
