I don't read french, so I don't know what that URL said, but device naming is 
not an issue.
All you need to do is change the partition type to fd "Linux raid autodetect", 
then either:
1) Compile all the raid/ide/scsi drivers you need into the kernel, and all 
your arrays will be automagically created on startup.
2) Add an entry like at the bottom of page 1 of the linuxdevcenter article, 
except all you actually need is this:

DEVICE partitions
ARRAY /dev/md0 uuid=8ef83d67:79b230ba:6cc967c3:208b9224

I have a SATA card that doesn't have in kernel drivers, so I have to load a 
module, which naturally means the kernel can't autostart all my arrays, but 
mdadm can without me having to tell it any device nodes.
