I have this exact same setup, and it's working great.
You do have the correct partition types setup, right? The underlying RAID partitions should be type 0xfd (Linux raid autodetect). Also, where are your disks attached - are you really sure that the kernel has drivers for your host controller in the initrd - perhaps you should edit the linuxrc (I think) script file to cat the content of some /proc files to prove that the disks are known to the kernel. Perhaps even add sfdisk to the initrd, and have it dump out the partition tables etc. at boot time.
For example, fdisk says this about one of my disks:
SEVERN:~$ sudo fdisk /dev/hdg
The number of cylinders for this disk is set to 30515. There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with: 1) software that runs at boot time (e.g., old versions of LILO) 2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK)
Command (m for help):
Disk /dev/hdg: 251.0 GB, 251000193024 bytes 255 heads, 63 sectors/track, 30515 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes
