Nvidia driver 1.0.8178

>Description:

Even when running fxtv with -disableDirectV, it tries to initialize
some DGA stuff in tvscreen.c. This makes it fail with newer NVIDIA
drivers which are broken w.r.t. DGA.

>How-To-Repeat:

Run "fxtv -disableDirectV" with an NVIDIA driver which has broken
DGA support:

andre at bali:~>fxtv -disableDirectV
X Error of failed request:  XF86DGANoDirectVideoMode
  Major opcode of failed request:  138 (XFree86-DGA)
  Minor opcode of failed request:  1 (XF86DGAGetVideoLL)
  Serial number of failed request:  24
  Current serial number in output stream:  24

>Fix:

Add this patch to multimedia/fxtv/files. It will disable
DGA stuff completely when -disableDirectV was given on
the commandline.
