Nope, not an issue with anything but the IDE controller/firmware in those
few systems.

The 8GB limit isn't present for the on-board SCSI in the platinum G3,
wasn't present in the on-board SCSI of previous PowerPC Macs, and wasn't
present in later PowerPC Macs either (the first revision of B&W G3 had
completely different issue regarding IDE UDMA support).  And 48-bit LBA
became a standard feature of the on-board IDE in the 2002 "Quicksilver" G4
and all later models.
