Everything else is the same as before - I even installed from the very same DVD. My conclusion is therefore that I really had a disk that was broken in a way that normal tests will not detect. Hence, my tip to anyone having a similar experience: Don't blame the driver, nor the motherboard/chipset - just replace the drive. It would of course be even nicer if the error message could spell this out somewhat clearer too, but I guess the "I/O error" in the middle is a fair hint in retrospect.
