Hello Izumi,

thx a lot for this wonderful tip. i looked up the pciide(4) man page and
went to fry's to buy a promise ultra66 card with the documented chipset and
... voila everything works fine now. both channels probed successfully and
full ultra-dma mode is working correctly.
thx again and HAPPY NEW YEAR!
