Is there a ahci-devel list I am unaware of?  In the mean time, I
managed to pepper some of the Linux storage list with the same
question.  No dice yet.

Per folks more knowledgeable in kdump/kexec etc., here are some advantages -

1) This approach doesn't have the same resource constraint as that of
kdump approach like setting aside memory.
2) This would be more reliable on systems that uses AHCI.

Also, in the long run this component could be turned into one of the
many lowest level pluggable storage interface for crash dump
persistence and other components could be built on top to collect lot
more useful information.
