It would work with a real W.D. chipset controller, but NOT some of the clones. Turns out to be a real NO NO in the code, using registers explicitly stated as WRITE ONLY, and explicitly stated as 4 bits big, as a READ for status (trying to read the TOP 4 bits, which are stated to BE RESERVED and UNDEFINED !!!!). To make the long story short, we posted a fix to the net, see article 2608. This includes diffs and a uuencoded bootwd needed to correct the problem.
