This is just the job for an initramfs. They are *really*easy* to
make, and very flexible. mdadm-2.2 and later come with a little
script which (tested on Debian) makes a simple initramfs which
will recognise a kernel parameter (as passed by lilo's 'append')
like
rootuuid=97e58306:2c85fd85:2346b91e:aaca5fee
and will assemble the appropriate array a /dev/md_d0 and will then
mount a filesystem of there as root. If it doesn't do exactly what
you want, it is fairly easy to modify.
