Marcelo, you've been overlooking these updates for a bit too long now for your "let's throw them at -ac" to sound fair. IMHO of course. Also remember those are both production drivers tested thoroughly in FreeBSD, plus you have your own testing releases -- or at least that's how I thought '-pre' was meant, and so did Pete Zaitcev apparently (Message-ID: <20021217142235.C8233@devserv.devel.redhat.com>). -- Tomas Szepe
