Some questions, does fc6 and fc3 both run on the same computer or two different computers? 2) Have you brought fc6 up and then done a speakup start attempt using modprobe yet? 3) If you got speakup talking with 2, have you done the instructions in the howto to make an initrd file yet? 4) If you've done all of that have you tried using acpi=force as an additional boot parameter sometimes that helps systems locate things better.
