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