Thanks. So there is no real chance to fix it but to override this
function?
The strange thing is that the PROM prompt handles it correctly:

| ok devalias scsi /iommu/sbus/espdma/esp
| scsi isn't unique
Non-unique devalias entries are NASTY. Get rid of them, for example
your second definition of scsi could be changed to scsidisk.
You should also check that any nvramrc entries do not cause conflicts,
it is common for nvramrc entries to refer to devalias entries, so you may need to also change an nvramrc entry to match any devalias change.

You can disable the use of nvramrc from the OBP prompt with
setenv if the entry isnon-essential, they are most commonly used
where there is a mirrored root disk.
