Ok.

Ok. But we have a hint in the manual, that there _is_ such an
automatic fallback (or am I wrong?)

Yes. Auto-detecting the cdrom drive works this way.

Output follows at the end of this mail.

Ok.

My first experience with rescue mode. Well, it worked quite easy.
After updating initramfs, booting the system worked.
(/etc/initramfs-tools/module was empty before I added ide-generic! )
Only one note: normally there is the hint "rescue mode" in the
left corner at the top of the screen. When running rescue mode on a
low memory machine, there is only "low memory mode" displayed,
nothing about that rescue mode is active.
