Hi,
I just commited fixes to wdc_obio.c (rev 1.16) to properly support ata-4
controllers, including Ultra-DMA. I tested this on a dual-USB ibook,
in Ultra-DMA 66 and Ultra-DMA 33 (my test program confirmed that Ultra-DMA
is used: 27MB/s for Ultra-DMA 33, 45MB/s for Ultra-DMA 66).

Please report any problems using send-pr (and please test, even if you
have an older IDE controller :)
