'md' and the drivers for you disks are not compiled into the kernel but are present as modules in an 'initrd'. So the kernel parameter or md=0,/dev/hda1,/dev/hdb1 is ignored and the code in the inird is completely responsible for assembling md0. You have a look at what it does: mkdir /foo mount -t cramfs /initrd.img /foo ^^^^^^^^^^^ You have to find the initrd that is being used and use that name here. Then have a look at etc mdadm.conf in /foo. Once you understand the problem you will need to remake your initrd to get this right.
