That's not entirely true. Etch does support RAID-10, just not the installer. What I would suggest is first to do a minimal installation to a small RAID-1 partition, including GRUB to the MBR. Then, once you have booted into this system, use the system tools (cfdisk, mdadm, & lvm) to set up the rest of the drive(s) as RAID-10 (with or without LVM). Then, do a debootstrap installation of a complete system into this. Finally, your RAID-1 partition becomes your /boot partition. Not the most direct route, but it works.
