Well, I got this running relying on /dev/dm-x device mapping and it works.

I was just figuring out why BIOS is changing DDF volume names every 
time... Is this meaning that BIOS try to autodetect RAID array-on-disk 
signatures every reboot instead of reading configuration from NVRAM? I 
think that this can be an issue for distro installers... Isn't it?
