Hi Cicero, thanks for this wonderful report. There has been some little change in version 1.0.2 which might interest you.
First of all, ATA device now acts like former 'emergency mode' kernel before, meaning that you should be able to install AROS and boot it flawlessly on a SFS partition, which is faster and safer. FFS has the habit of crashing and creating holes in the filesystem, which is really bad. And it's painfully slow.
'emergency mode' kernel has been kept as a desperate last hope, though.
Also: look in the "backup" drawer of AmiBridge, you should find right settings for AmigaOS 3.x screenmode and overscan.
