I had this idea too, but what I have to say is that in the first partition is running WindowsXP. I've created the raid while installing MS Windows. Using "dmraid -ay" and devfs, I was able to create the proper devices in "/dev/mapper" , but this is no more because I want udev; since I use udev these devices ("/dev/mapper/sil<*>{1,2,3,4}") are not in /dev any more.

Ok, I don't use mdadm, but that looks completely screwed up to me. First, if you want the md driver to autodetect your raid arrays, the
partitions types on sda, as well as sdb4, need to be 0xfd.  Use fdisk to
fix them.  You also need to create the arrays with "persistent superblocks."

But, more importantly, your partition sizes are not even close to a
match for raid 0.  For example, /dev/md1 consists of sda2 and sdb2
according to your mdadm.conf file...but sda2 is ~92GB while sdb2 is
0.5GB.  That means /dev/md1 (assuming raid0 or raid1) should come out
about 1GB total size, wasting 91GB of space!!!!
