This should be supported under the tulip driver
(http://cesdis.gsfc.nasa.gov/linux/drivers), which supports the whole tulip
chipset family of cards. I've been using the tulip driver with a DE500 in
100M-FD for about a month now, with 0 problems. Clocked it at up to
30Mbytes sustained file transfer, still have to do some actual testing
soon...
