Apple actually had a remote debugger that (ab)used the FireWire DMA to get access to the RAM. I used it several times when debugging drivers on OS 9.
I had thought that the OS X FW drivers didn't map any RAM until a driver requested some 1394 address space, but apparently that isn't the case... That would be the sane and easy way to fix this.
