New Revision: 274378
URL: https://svnweb.freebsd.org/changeset/base/274378

Log:
  Based on some BIOS configuration (GGC register in host bridge, bit 1),
  IGP may declare subclass as either VGA-compatible, or non-VGA.  The
  difference is that in the later case, IGP does not claim VGA cycles.
  Other than that, the device functions normally, and agp_i810 should
  attach to it.
