You can do a custom boot SDcard or USB thumbdrive if you have an empty bootable SFS/00 rawimage. I used Windows to write the rawimage to the SDCard and Aros x86 to copy the AmigaOS 4.1 CD contents to the SDCard then add the new driver saved to a Fat32 formatted USB thumbdrive to the SFS/00 SDcard. not a problem for me but not something for a new user buying what should be a polished product. Plus I used a working system to create the rawimage file for possible future problems. I have an unique perspective on this as I ran a Sam440ep-flex with the RadeonHD driver for over two years. During this time my Radeon 9250 went bad so I would not have been able to boot my system using the the original install cd.
Thank you for 're-clarifying that issue again. Since the CDs are not copy protected, one could just build a CD with the correct versions of whatever driver they wanted, at least this is what I did to install Ubuntu with the install guide, updated kernels and such; or is this in need of someone else doing it for you? I don't know, I forget...
