K.Y.: Youre _theory_ ( about "can solve the issue on hand using modprobe rules") is wrong for:
-- OpenSUSE
-- Ubuntu
-- Debian

Why You think, what theory can solve problem in other case?

How about LiveCD ?


But "patch against the ata driver" -- solve problem 100% / 100%

But Hyper-V admins need "result" -- if You can fix _all_ what need by "modprobe rules" -- fix issue in:


Kernel:
3.5 -- done
3.4.latest
3.3.latest
3.2.latest

Distro:
-- Arch Linux
-- Chacra
-- _all_ LiveCD
-- Gentoo
-- Debian
-- Fedora

As I said, if the ata_piix driver is a loadable module, we can solve the issue
with modprobe rules. If it is not a loadable module we cannot obviously solve
the problem with modprobe rules and we will need the ata patch.
