Lincoln's code works great. The only gotcha is if a laptop needs ACPI suport in order to recognize the firewire bus like a lot of the Sony Vaio's. I created a version using Lincoln's code but compiled a new 2.4.22-xfs kernel with ACPI support built in. I can now boot Knoppix from my Sony Vaio PCG-R505GCP.

Thanks for all the help Lincoln!!
