Hi,

if you KNOW a certain ata port is not connected (for example in a
netbook where there's just nothing there possible), we still probe
the port currently and waste time. This time is a significant part of
the total boot time.

This patch series introduces a module parameter that can be used
to tell the kernel which ports to skip, and the second patch
adds a DMI list for known setups so that for known cases
users don't have to add any parameters at all.
