I think the easiest fix try for that theory is to get the CDROM on the warpdevice as well.
Yes, but you need a little Hardware-Hack to get it working in the A3000 !
It is incompatible with the A3000's motherboard SCSI controller - replacing the A3000's SCSI chip to rev. 08 solves the problem.
And the device is called warpdrive.device
