Replying to an old post, are you still interested in trying it?
I just got it up for first time on my A3000. I have not done much yet but plan to play around with it soon. I think you need to get a recent daily (

I believe the reason you got stuck at the boot screen with the A3000 is that you try to boot from SCSI and AROS has no SCSI driver at the moment. You need to load a Commodore scsi.device somehow, perhaps by using a boot floppy, or build your own kickstart with a scsi.device inside it (like I managed to do a few days ago). Hopefully there will be an AROS SCSI device at some point, but for now I use a Commodore scsi.device with it.
