This has been broken for a while, so a few more weeks(or more) will not hurt. Also, I need to catch up with ZONE_DEVICE myself and I will be on vacation for a few weeks, so that is it. Feel free to re-use anything you find useful in these series(in case you find something). Thanks -- Oscar Salvador SUSE L3
