Well, does the order in hins affect the order of device probe? I thought not... In any case, if the video driver(s) has not been probed when syscons is being probed, the video drivers will be initialized through back-door (yes, this is a kludge). So, the probe order shouldn't be much of a problem... Kazu To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
