The solution to getting the D-Link dge530t gb card working was to use the driver from the Marvell site and NOT the driver from the D-Link site. The D-Link driver would not compile. The Marvell driver compiled fine, as long as the kernel source rpm was installed. And now that it has been compiled on one machine running SLF305, it can just be copied to the new machine modules directory. Then, when the D-Link card is installed, kudzu will find it on the next reboot.
