Hi

The raid system will be detected with DM-raid. Ubuntu does not use
this by default. Suse does, so it can even install on a "fake" raid
system. I did it once to my Asus P4P800 with 2 disks in Raid 0. This
was very succesfull.

You can use ubuntu for this, but you should not expect it to be able
to install directly onto the raid system. Once installed on another
harddisk you can prolly run "apt-get instal dmraid" then "modprobe
dmraid" and some partitioner to be able to see the partitions on the
disks.
