The contrary is also true, for modern drivers/ide conversion of libata PATA
driver to use drivers/ide should usually be a matter of an hour or two.

I think that the conversion of libata drivers for PATA hardware that is not
supported by drivers/ide currently should be doable by somebody knowing
both subsystems in less than 24h.  I'm not doing it only because it will make
me a maintainer of even more host drivers than currently and I don't have a
time for it.  I'll happily accept patches though.

Thanks,
Bart
