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