I guess the --with-*abi options are defaults now anyway so should not be 
explicitely needed (but it does not hurt either).

Nothing special should be needed. I just use:

-drive if=none,id=cd,file=aros-sam440-ppc.iso,format=raw \
-device ide-cd,drive=cd,bus=ide.0

where ide.0 is first port of sii3112 and ide.1 is second port.

That should not be needed because you could just attach an image as an HDD 
with

-device ide-hd,drive=hddrive,bus=ide.0

after defining -drive with id=hddrive but the sdcard reader in Sam460ex is 
a USB device so it could be emulated as USB storage with

-device usb-storage,drive=hddrive,bus=usb-bus.0

which may work but I think it would be slower and may have problems due to 
u-boot bugs present in the Acube firmware.

You don't need to relay messages (thanks for doing it though), but 
developers who have something to say could contact me directly via email 
or on one of the lists I'm on.
