As a workaround, will I be able to boot NetBSD on my Amiga 500 (once all
the hardware and accelerator is supported) if I softboot the Workbench
3.0 kickstart file that was supplied to developers when 3.0 first came
out and then LoadBSD from there?

Boot Sequence:  

WB1.3 -> Load 3.0 Kickstart file & reboot -> Boot 3.0 -> Boot NetBSD
