Hm, well, ok, I created a grub.cfg with grub-mkconfig and edited it:

menuentry 'Debian GNU/Linux, with Linux' --class debian --class 
gnu-linux --class gnu --class os {
        insmod part_msdos
        insmod ext2
        insmod raid
        insmod mdraid
        set root='(/dev/sdd,msdos1)'
        search --no-floppy --fs-uuid --set e62e0c56-2531-4ec4-a839-1835b8b0a8cc
        echo    'Loading Linux ...'
        linux   /vmlinuz- iommu=noaperture root=/dev/md0p2 ro  

Now I can boot from /dev/sdd, but the kernel panics because it can't
mount the root filesystem (/dev/md0p2). Entries in /etc/fstab on md0p2
are correct. I take it the md-devices aren't up/accessible in time.

Any idea what's missing? Like there's no RAID support in grub?
