  Now things start to get *REALLY* weird.

* Using VIDEO_CARDS="i965" in make.conf enables DRI2 hardware acceleration
* But it requires the "classic" USE flag for mesa
* The "xorg" USE flag also makes mesa require the "gallium" USE flag
* Building mesa with *BOTH* "classic" and "gallium" works
* And it runs in 1366x768 mode
* And it runs *ONLY* in 1366x768 mode.  xrandr does not change the
  resolution, notwithstanding the gazillion modes it lists
* I went back to mesa without the "xorg" and "gallium" flags to simplify
  my setup
* Again, it runs 1366x768, and *ONLY* 1366x768.  But it does have
  hardware acceleration
* And yes, I did try replacing the xf86-video-intel driver with
  xf86-video-modesetting.  No X.
* So the one change I've made after all this fooling around is to change
  the VIDEO_CARDS setting in make.conf from "intel" to "i965".

  The net change is that...
* the TV displays in native 1366x768 mode, and *ONLY* 1366x768 mode
* X now has hardware acceleration
