CMD649 hardware raid support

["Sönke Ruempler" <ruempler@topconcepts.com>]

hi ide-devels,

i have a cmd649 hardware raid controller with 2 maxtor hdd's. in the
controller bios setup i bound them to a raid-1 array.

now linux finds the card

CMD649: chipset revision 2
CMD649: not 100% native mode: will probe irqs later
CMD649: ROM enabled at 0xeff00000
    ide2: BM-DMA at 0xd600-0xd607, BIOS settings: hde:pio, hdf:pio
    ide3: BM-DMA at 0xd608-0xd60f, BIOS settings: hdg:pio, hdh:pio

hde: attached ide-disk driver.
hde: host protected area => 1
hde: 160086528 sectors (81964 MB) w/2048KiB Cache, CHS=158816/16/63
hdf: attached ide-disk driver.
hdf: host protected area => 1
hdf: 160086528 sectors (81964 MB) w/2048KiB Cache, CHS=158816/16/63

and as everybody can see linux IGNORES the raid. imho the hardware raid
array should be transparent to the os and show 1 device to it. linux seems
to simply ignore this.

here the lspci:

                Status: D0 PME-Enable- DSel=0 DScale=3 PME-


So what can i do?
