NetBSD/Amiga does not support reselection.
Turning reselection on will not buy you anything as a result. I'm not
sure if turning on reselection causes NetBSD to fail.
Reselection would actually be a useful thing to have, esp. if you have a
tape drive. It's not too hard to implement. The messy part will be DMA -
when a device disconnects, you need to stop the DMA and determine exactly
where it left off so the transfer can be resumed at the right place.
If I had good DMAC docs, I'd try this myself. That'll have to wait until
after I finish the Xylogics SMD driver for the Sun3 I just got today.
