Log message:
  PInS data on later cards (G200 and later) contains information about the
  physical bus used for the card.  This allows accurate detection of PCI
  cards that use a PCI-to-PCI bridge with an AGP chip.
  
  Correctly disable DRI on PCI cards used with pre-3.2 DRM. Previously the
  test was performed based on PCI ID (see above for why this is wrong) and
  was done *before* the DRM version was known.
  
  Bug #3759: <https://bugs.freedesktop.org/show_bug.cgi?id=3759>
  Correctly determine the PLL reference frequency from the PInS data.
  Previously the wrong bit was tested.  Blame the dumb programmer that used
  cut-and-paste (that would be me).
