We'll see... I would really like to ignore MDMA. For the reasons just
outlined in replies to Linus, PATA support is quite useful in limited
situations, but is not at all the focus of the driver. When situations
arise where special support for some PATA situation is needed, I will
most likely just say "use drivers/ide"...
