If I remember correctly, it was only true for 68k models (2GB limitation in ROM or something).
Nope, Drive Setup in 7.6 and later installed the 'ruby' patch into a patch partition on the hard drive to fix this limit in the old ROMs that is loaded when the hard disk driver is loaded very early in the boot process. The PCI Power Macs and PowerBook 5300/1400/190 was the first Macs with large volume support built into their ROMs, and these Macs supported large volumes under System 7.5.x. Mac OS 7.6 backported large volume support onto all 68040 and PowerPC Macs (68030 Macs did not get this backport). You may be confusing it with HFS+, which was indeed only bootable under PowerPC Macs, probably something have to do with how the System file in the HFS Wrapper used to boot old Macs that do not have HFS+ support in ROM from HFS+ volumes was designed.
