Log Message:
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.
