Tested on a ASUSTeK M2N-VM DVI with good results. Only problem found was 
with a CF card in a SATA-CF adapter. It lies that it can handle DMA but 
fails miserably. Searched the web but could find no way to disable DMA when 
using CAM-ATA.

Here is the inital rescan result after attaching it and the timeout when 
doing an identify:
