More details follows. With old ATA driver I got this devices:
acd0: DVDROM <ASUS DVD-E616A/1.08> at ata0-master UDMA100
acd1: DVDR <PLEXTOR DVDR PX-740A/1.02> at ata0-slave UDMA33
ad8: 114473MB <Seagate ST3120827AS 3.42> at ata4-master SATA150
ad12: 238475MB <Seagate ST3250620AS 3.AAC> at ata6-master SATA150
...
Trying to mount root from ufs:/dev/ad8s1a

With new one only
acd0: DVDROM <ASUS DVD-E616A/1.08> at ata0-master UDMA100
acd1: DVDR <PLEXTOR DVDR PX-740A/1.02> at ata0-slave UDMA33
detected, and of course mount root from ufs:/dev/ad8s1a failed.
