Check to see if /sbin/dhclient is disabled. Are you loading drivers manually with insmod anywhere? If it's not any of those things, the most probable cause is that I screwed up the modifications to the /etc/hotplug/usb.map file for standalones. Take a look at the file in vi or joe. The script should have inserted some new entries under the "usbnet" heading to support the latest adapters in Jamie's backport. These include the USB200M, D-link dub-e, etc.. Check to see if the FA120 entry is still there under the proper heading.
