Japanese people have tried. ITOH Yasafumi one of the BSD folks has done some very significant reverse engineering work on the Delkin and friends to get PIO mode working properly. Our libata driver is basically built on that work. > I have a brand new spare card here (with a Delkin 2GB 305x speed CF card in it) and am willing to send it to a kernel developer interested in working on a driver for it (Mark Lord?). Alternatively if anyone wants me to dump registers under Windows, test drivers etc I am prepared to put in the time to help in these ways. The current state of affairs is the libata pata_ninja32 driver. That should give good PIO performance. If you want DMA I think you'll have to do it yourself however, or hope the BSD folks get it working reliably.
