Damn, I guess I was too fast with saying "Fixed"...
RAID 1 is ok, but I still need "ide=nodma"

Without it, I get further than I used to, but I now get stuck after
"Remounting root filesystem in read-write mode    [OK]"

The next step would be:
"Setting up logical volume management" or something like that

So I guess I have to keep the "ide=nodma"...
