I wasn't aware of that. Perhaps in this special case, the PHY/MAC FPGA code 
could be reprogrammed to operate at 100Mbit, just to make it work with the 
Overo? 

If that is sufficient bandwidth would depend upon the application, but it is an 
interesting experiment to try out. 

I already got GNU Radio running on the Mac from sources. I also have been 
working on the Gumstix Overo for about 2 years now with OpenEmbedded, so it 
should be interesting just to port it across and run it off the overo.
