The patch below may be of some use. It adds partial RAIDframe support to
the i386 ramdisk CD and install program.

You still have to set up the RAID array in the shell before starting the
installation, but the patched install program will then do everything
except install the kernel and bootloader, which you can manually install
on small boot partitions on each drive.

(A note on building the ramdisk CD: you have to update the MAKEDEV in
/dev, as this is the one actually used by the build rather than the one in
the source tree.)
