Hannes Reinecke 6a690df5c8 [PATCH] scan all enabled ports on ata_piix
ICH6 spec defines the PORT_ bits as:

PORT_ENABLED (R/W):

  0 = Disabled.  The port is in the off state and cannot detect any
  devices.

  1 = Enabled.  The port can transition between the on, partial, and
  slumber states and can detect devices.

PORT_PRESENT  (R/O)

  The status of this bit may change at any time.  This bit is cleared
  when the port is disabled via PORT_ENABLED.  This bit is not cleared upon
  surprise removal of a device.

So from a textual view it is not necessary that PORT_PRESENT _must_ be set,
especially if a device detection has to be done anyway.  And, in fact, this
is the view that ACER has been taken with its new Laptops (e.g.  Travelmate
4150).

And the definition of PORT_ENABLED / PORT_PRESENT is mixed up, btw.
