  Log:
  Minimal fix to prevent crashes when an AGP v2 card is used with the new v3 VIA
  chipsets, based on Linux's via-agp.c.  On boot, the system selects which AGP
  version to use based on the inserted card.  If v2 was chosen, the chipset
  needs to be programmed with the v2 registers still.  Also included in kern/69953
  are changes to make the programming of the v3 registers match linux, but that
  will be left out until the need to do so is confirmed (want specs or a tester).
