No problem, I am interrested in a well working Debian ;)

It is! And in special the fact that it even doesn´t work if someone is
partitioning the entire (restricted to 128 GB) space with MacOS, and let
Debian just change the filesystems at the existing partitions, as I
reported above, ...

I just wanted to point at the fact, that MacOS 9 (and 8) limits are at 42
terrabyte, and the 128 GB is just a limit of the onboard controller of the
early G4s. So a solution that will scan for the controller in use (!)
would be needed, as the problem doesn´t occure at the same machine, with
several addon cards for SATA, LVD-SCSI, or ATA100/133.

Also the general HFS+ limits, 8 exbibyte (EiB), seem to be valid, even if
MacOS "just" can use the 42 terrabyte.
