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.
