Owning a G4 (digital audio) without large disk support, this seems intriguing as a way to use all of my 160 GB disk. Intech's kext would allow me to create a second 32 GB partition, but the first partition must still fit completely in the first 128 GB of the disk so that OS X can boot from it. And it requires the OS 9 version for a dual boot machine like mine. All in all, more than I paid for my external firewire case.
So I'm still stuck with the limitation's of my G4's ROM, and I gave up on partitions a long time ago, after endless shuffling of data across partitions to make space where I needed it when I needed it.
For now, I think I'll stick with my external firewire drive.... how about a ROM patch, Intech???
