I was unaware of this patch (which looks a lot more thorough than mine). Thank you for the link. His patch makes the change to dio_find() , but I don't see any changes to drivers/net/hplance.c or drivers/video/hpfb.c - are the changes I made there not needed? those two treat a return value of 0 from dio_find() as an error as far as I can tell...
