http://www.murty.net/ataraid/ <---very good documentation, used a lot from 
here.  I think this is going to be your biggest help.

I did the same thing, my / is on my ata 133 onboard raid card.  my fstab looks 
like this:

/dev/ataraid/d0p2       /               auto    
defaults,noatime,nodiratime,notail      0       1

but i also had to add a kernel command line option.

image=/vmlinuz
        label=Linux
        read-only
#       restricted
#       alias=1
        append="ide3=0xd400,0xd002 ide4=0xb800,0xb402"
- From /proc/pci
RAID bus controller: Promise Technology, Inc. PDC20276 IDE (rev 1).
      IRQ 3.
      Master Capable.  Latency=32.  Min Gnt=4.Max Lat=18.
      I/O at 0xd400 [0xd407].
      I/O at 0xd000 [0xd003].
      I/O at 0xb800 [0xb807].
      I/O at 0xb400 [0xb403].
      I/O at 0xb000 [0xb00f].
      Non-prefetchable 32 bit memory at 0xd5800000 [0xd5803fff].

Also, I compiled my own kernel, so I made sure I had all the ata raid drivers 
built into my kernel.
