Anyway, I would be happy if the IDE driver would "just not do that". :)
I can see the reasoning where the device just doesn't function properly
with DMA at all (like on some Compact Flash-to-IDE adapters where the
card claims to support DMA but the DMA lines aren't wired through in the
adapter properly). In that case not disabling DMA would render it
useless. The IDE layer could keep track of whether DMA was previously
working on that device however, and not disable DMA on reset if it had
previously been working.
