Thanks to your patch for ata-raid.c and ata-raid.h
FreeBSD can use the raid-1 with only 1 disk
Thanks you very much!

ad4: 194481MB <Maxtor 6L200M0 BANC1G10> at ata2-master SATA150
ar0: WARNING - mirror protection lost. RAID1 array in DEGRADED mode
ar0: 194480MB <VIA Tech V-RAID RAID1> status: DEGRADED
ar0: disk0 READY (master) using ad4 at ata2-master
ar0: disk1 DOWN no device found for this subdisk

%mount|grep ar0s1
/dev/ar0s1 on /raid (ufs, local, soft-updates)

Your patch could maybe be merged in RELENG_6 before 6.0-RELEASE ?
FreeBSD support hotplug SATA for this controller?
