        external/mit/xorg/server/drivers/xf86-video-wsfb/Makefile: revision 1.6

wsfb: Disable broken DGA support:
  - dga(1) crashes X server since pScrn->AdjustFrame is NULL.
  - If nop is provided as pScrn->AdjustFrame, dga(1) crashes X server *AND*
    kernel. This is because DGA uses physical address of framebuffer via
    /dev/mem (oops!), but we provide only mmap(2)'ed virtual address.
