OK, it looks like the installation did not create a correct initrd,
probably because the driver was not where it could find it. I should have
thought of that.

You will have to get the installer to create an initrd with the driver for
the raid controller in it, or you will have to manage to load it somehow
during boot, or build a kernel with it in.

Have a look at mkinitrd and see if it can be forced to include certain
drivers. If so, you can create the needed initrd on another machine, put it
on a floppy, boot from the CD with something like:

   linux initrd=/dev/fd0 root=<your root file system> ...

You may need to dd the initrd onto the floppy ... Not sure
