I think it's worth to be supported. The RAID mode of storage
controller seems to be a default BIOS configuration in all modern
desktop computers. I think most desktop users don't configure any real
RAID and continue to use their disks as separate devices. If at least
this RAID configuration is supported it would be a great progress.
BTW attaching the dmesg output when booted from the 6.2 installation
media in RAID mode.
