It seems to work fine for 100Mb. I can't verify if gigabit Ethernet works since this is the only such device on my LAN. If you make the jump to the latest kernel Ethernet will work, but you will have to make changes for your SATA drives to work, since they will need the SCSI emulated sata_nv module. Which means you'll have to build you a custom initrd.img file or you won't be able to boot to the SATA drives anymore. My advice is to INSTALL the new kernel, DO NOT UPDATE it. That way you have a fallback incase you miss something in the transition.
