RAID-0 Autodetection fails

Hello everybody,
I am installing Linux SuSE 8.0 with kernel version 2.4.18-4GB. This
kernel should have already contain the Software-RAID module as
advertised by SuSE.
I have 3 equal drives. For simplicity I installed complete Linux only in
a drive hdb(the boot and the root is in this normal drive) and now I am
trying to make a RAID level 0 with the rest 2 drives called hdc and hdd. 
I have made these two drives into a RAID-drive called /dev/md0 with
YaST2 help and it was successfully mounted and used.
But each time I rebooted the system, this /dev/md0 could not be
recognized at startup and all data in /dev/md0 was lost as well. I
needed to mount it again afterwards, that made it a silly idea.
What is wrong ? Any hints and helps are gladly welcomed.
