It is hackish at the moment because as you've rightly guessed, I haven't gotten around to finishing it. It also doesn't work perfectly - I sometimes need to rmmod and insmod after booting a new kernel to get the link to come up. But, apart from that, it works fine. Attached. (Jeff, I'm sure it doesn't need saying, but please don't apply!) Regards, Nigel
