CONFIG_AGP
  AGP (Accelerated Graphics Port) is a bus system mainly used to
  connect graphics cards to the rest of the system.

  If you have an AGP system and you say Y here, it will be possible to
  use the AGP features of your 3D rendering video card. This code acts
  as a sort of "AGP driver" for the motherboard's chipset.

  If you need more texture memory than you can get with the AGP GART
  (theoretically up to 256 MB, but in practice usually 64 or 128 MB
  due to kernel allocation issues), you could use PCI accesses
  and have up to a couple gigs of texture space.

  Note that this is the only means to have XFree4/GLX use
  write-combining with MTRR support on the AGP bus. Without it, OpenGL
  direct rendering will be a lot slower but still faster than PIO.

  You should say Y here if you use XFree86 3.3.6 or 4.x and want to
  use GLX or DRI.  If unsure, say N.

  This driver is available as a module.  If you want to compile it as
  a module, say M here and read <file:Documentation/modules.txt>.  The
  module will be called agpgart.o.

CONFIG_AGP_INTEL
  This option gives you AGP support for the GLX component of the
  XFree86 4.x on Intel 440LX/BX/GX, 815, 820, 830, 840, 845, 850 and 860 chipsets.

  You should say Y here if you use XFree86 3.3.6 or 4.x and want to
  use GLX or DRI.  If unsure, say N.

CONFIG_AGP_I810
  This option gives you AGP support for the Xserver on the Intel 810
  815 and 830m chipset boards for their on-board integrated graphics. This
  is required to do any useful video modes with these boards.

CONFIG_AGP_I460
  This option gives you AGP GART support for the Intel 460GX chipset
  for IA64 processors.

CONFIG_AGP_VIA
  This option gives you AGP support for the GLX component of the
  XFree86 4.x on VIA MPV3/Apollo Pro chipsets.

  You should say Y here if you use XFree86 3.3.6 or 4.x and want to
  use GLX or DRI.  If unsure, say N.

CONFIG_AGP_AMD
  This option gives you AGP support for the GLX component of the
  XFree86 4.x on AMD Irongate, 761, and 762 chipsets.

  You should say Y here if you use XFree86 3.3.6 or 4.x and want to
  use GLX or DRI.  If unsure, say N.

CONFIG_AGP_SIS
  This option gives you AGP support for the GLX component of the "soon
  to be released" XFree86 4.x on Silicon Integrated Systems [SiS]
  chipsets.

  Note that 5591/5592 AGP chipsets are NOT supported.

  You should say Y here if you use XFree86 3.3.6 or 4.x and want to
  use GLX or DRI.  If unsure, say N.

CONFIG_AGP_SWORKS
  Say Y here to support the Serverworks AGP card.  See 
  <http://www.serverworks.com/> for product descriptions and images.

CONFIG_AGP_ALI
  This option gives you AGP support for the GLX component of the
  XFree86 4.x on the following ALi chipsets.  The supported chipsets
  include M1541, M1621, M1631, M1632, M1641,M1647,and M1651.
  For the ALi-chipset question, ALi suggests you refer to
  <http://www.ali.com.tw/eng/support/index.shtml>.

  The M1541 chipset can do AGP 1x and 2x, but note that there is an
  acknowledged incompatibility with Matrox G200 cards. Due to
  timing issues, this chipset cannot do AGP 2x with the G200.
  This is a hardware limitation. AGP 1x seems to be fine, though.

  You should say Y here if you use XFree86 3.3.6 or 4.x and want to
  use GLX or DRI.  If unsure, say N.

CONFIG_AGP_HP_ZX1
  This option gives you AGP GART support for the HP ZX1 chipset
  for IA64 processors.
