+       help
+         Some "legacy" VGA devices implemented on PCI typically have the same
+         hard-decoded addresses as they did on ISA. When multiple PCI devices
+         are accessed at same time they need some kind of coordination. Please
+         see Documentation/vgaarbiter.txt for more details. Select this to
+         enable VGA arbiter.

+         Reserves space in the kernel to maintain resource locking for
+         multiple GPUS.  The overhead for each GPU is very small.

+       help
+         Many laptops released in 2008/9/10 have two GPUs with a multiplexer
+         to switch between them. This adds support for dynamic switching when
+          X isn't running and delayed switching until the next logoff. This
+         feature is called hybrid graphics, ATI PowerXpress, and Nvidia
+         HybridPower.
