Can't dump on ATA RAID in 6.0-BETA3

[Daniel O'Connor]

Hi,
I can't set ar0s1b as my dump partition in 6.0-BETA3, ie
andenes# dumpon /dev/ar0s1b
dumpon: ioctl(DIOCSKERNELDUMP): Operation not supported by device

From dmesg..
atapci0: <VIA 6420 SATA150 controller> port 0xbc00-0xbc07,0xc000-0xc003,0xc400-0xc407,0xc800-0xc803,0xcc00-0xcc0f,0xd000-0xd0ff irq 20 at device 15.0 on pci0
ata2: <ATA channel 0> on atapci0
ata3: <ATA channel 1> on atapci0
...
ad4: 305245MB <WDC WD3200JD-00KLB0 08.05J08> at ata2-master SATA150
ad6: 305245MB <WDC WD3200JD-00KLB0 08.05J08> at ata3-master SATA150
ar0: 305245MB <VIA Tech V-RAID RAID1> status: READY
ar0: disk0 READY (master) using ad4 at ata2-master
ar0: disk1 READY (mirror) using ad6 at ata3-master

I have been able to dump on ATA RAID in 5.4 (using a Promise FT100 TX2) so
I think this is a regression.
