HP SmartArray 6404 card not recognized completely - only first 2 channels and can not attach properly

[Tomaž <tomaz.borstnar@xxxxxxxx>]

I have DragonFlyBSD 2.01 running on HP DL 360G4p 
(http://h18004.www1.hp.com/products/servers/proliantdl360/benefits-g4p.html?jumpid=reg_R1002_USEN) 

with additional 4 port SCSI CARD (HP SmartArray 6404 - 
http://h18004.www1.hp.com/products/servers/proliantstorage/arraycontrollers/smartarray6400/?jumpid=reg_R1002_USEN) 
which is connected to Hp MSA20 (box with 12 SATA drives for simple JBOD 
or RAID - configured as 12 JBOD volumes). DFlyBSD recognized the card as:

ciss0: <HP Smart Array 6400> port 0x4000-0x40ff mem 
0xfdff0000-0xfdff1fff irq 7 at device 4.0 on pci11
ciss0: using 256 of 1024 available commands
ciss0: error sending BMIC ID_CTLR command (35)
device_probe_and_attach: ciss0 attach returned 35

But it can not use it. But during boot machine sees lots of disks, but 
this is probably via BIOS?

pciconf -l output:
ciss0@pci11:4:0:        class=0x010400 card=0x409c0e11 chip=0x00460e11 
rev=0x01 hdr=0x00
none3@pci11:5:0:        class=0x010400 card=0x409d0e11 chip=0x00460e11 
rev=0x01 hdr=0x00

It also shows HP SmartArray 6400EM card which is part of the same 
physical card.

Is there anything that could be done for the driver to attach properly 
to the card and see those disks? FreeBSD 7 works if it helps.

Thanks in advance.
