pciide0 at pci2 dev 3 function 0: CMD Technology PCI0646 (rev. 0x03)
   [ ... ]
   
   I have no clue if this is a driver issue or the CMD Technology PCI0646
   simply can not do Ultra-DMA. ISTR it is the latter, though. Which means:
   there is nothing we could do about it.


i believe the cmd0646 is the problem;  i recall an email from manuel
where he couldn't believe they used such a crappy pciide ic...
