A couple bits:
While Mac OS 8.1 introduced HFS+, only Power Macs can boot to an HFS+ 8.1 drive. 680x0 machines cannot boot to an HFS+ drive.
And Snow Leopard's preferred FS is HFS+! I don't know what you're talking about it being read only... It's HFS (Mac OS Standard) that Snow Leopard is read-only on.
