If you think about this for more than 30 seconds it's perfectly clear
why this is impossible.  The block striping is performed by the kernel,
which means the kernel must be fully read from the disk before it can
control striping the data blocks across the disks.  The machine BIOS
must load the kernel.  The BIOS isn't aware of Linux striping.  You can
boot from mirrored disks/partitions because /boot is contiguous on both.
 You can't boot Linux software RAID5 for the same reason you can't boot
Linux RAID 0, contiguous /boot.
