Enabling them is essentially "local root hole for anyone who can use the
DRI" because the DMA capabilities of the card could be used to scrape
physical memory for info. I might note that by default the DRI sets the
modes on /dev/dri such that only root can use it anyway, but hints for
Section "DRI" are so popular that basically everyone uses them without
knowing what it could mean (which, according to our current standards
for security of released drivers, is "DRI users can hang the machine").

GL stuff related to visuals. A requirement for pbuffers.
