I connected the cf to ide adapter to an ide to sata adapter and using this 
combination on sata_nv makes no troubkes whatsoever. So what goues wrong with 
pata_amd/amd ide driver? BTW, I found specs for the cf card on the sandisk 
website. Perhaps someone wants to check whether the amd drivers deal 
corretcly with the true ide mode implemented in the cf card?
