I'm preparing a commit to SVN that has the following:

  # video driver selection

  # priority of xserver-xfree86/config/device/driver
  set_db_priority "high"

  DRIVER_DIR=/usr/X11R6/lib/modules/drivers

  # Build list of available video drivers, omitting the atimisc, r128, and
  # radeon sub-modules (the ati driver knows when and how to load these).
  # v4l is not a display driver, and dummy is for advanced users.
  DRIVER_LIST="$(echo $(find "$DRIVER_DIR" -name '*_drv.o' 2>/dev/null \
                        | sed 's|^.*/\(.*\)_drv\.o|\1|' \
                        | egrep -v '(atimisc|dummy|r128|radeon|v4l)' | sort) \
                 | sed 's/ /, /g')"

  if [ -z "$DRIVER_LIST" ]; then
    observe "no video driver modules found in $DRIVER_DIR"

This looks to me like it will satisfy your request.

Comments?
