I did it with OS X on the internal drive, and it's more for picky FW Cards and FW Cases.

My case would boot with a new machine, but it depended on the FireWire cable as to whether it would boot. On the older machines, it wouldn't boot unless you started on a minimal OS X and used the OS X internal as the Helper drive. Works better than using OS 9 for the helper.
