thanks for the info. I will merge the IDE patch then (with the additional modification to enable high-IO, that is why I looked into it). btw, while making that change, I was also wondering that it would be simpler to enable the highio in the common ide-dma part, rather than in the chipsets tunings, the highio is completly unrelated to the fact we compile amd7xxx or viaxxx into the kernel or not. but I didn't made that change because the amd7xxx driver was working fine for me and also because of possibly broken chipsets with the 31th bit of the bus address disconnected, just to stay on the very safe side and not to trigger hardware (not software) bugs.
