23 introduced in XFree86 4.0. If you say Y here, you need to select
24 the module that's right for your graphics card from the list below.
25 These modules provide support for synchronization, security, and
26 DMA transfers. Please see <http://dri.sourceforge.net/> for more
27 details. You should also select and configure AGP
28 (/dev/agpgart) support if it is available for your platform.
