Comment 7 for bug 686859

I managed to install Ubuntu onto my Intel Matrix RAID 0 using the alternative install disk after some further experimentation.

Using Gparted I created a new MSDOS / MBR partition table and formatted the drives. Using an MBR partition table is important because GPT partition tables require the kpartx application to map the partitions. To my knowledge kpartx is not pre-installed in the altenative installation disk and programs cannot be installed on the fly like they can with live disks. I then booted into the alternative installation disk and manually formatted partitions as usual. Thankfully the alternative installer does not seem to have any problem installing GRUB.
