Good news, everyone!

 I tried an AMD card, and it is almost working. I have a lot of logs
 and info, but I will try to restrain the length of this message.

 There was no need to do anything special to get the card to work,
 other than figuring out how to deal with Linux, setting up drivers
 and OpenCL SDK & linking libraries to the right places, compiling
 soft, etc.

 First, PCI info [0] and some dmesg bits [1]. AMD drivers:
  amdgpu-pro-16.50-362463.tar.xz
  AMD-APP-SDKInstaller-v3.0.130.136-GA-linux64.tar.bz2

 Next, the good news: Xorg starts, and display works!.. Kind of:
  -- `glxgears` window is flickery, has parts of gears missing,
     and does not look good in general;
  -- xterm window has the rectangular cursor shapes plastered
     all over, in random places;
  -- full-screen (1600x1200) `glxgears` is slower than expected,
     and the performance varies suddenly [2];
  -- VDPAU works, but I suspect it's not using the GPU [3][4];
     I haven't figure a way how to force the use of GPU. Also,
     the main window with text looks OK most of the time (when
     doing the video test and in the end, in particular), but
     show a smaller black rectangle in top left corner of the
     screen instead of the video samples;
  -- it almost feels like the DMA and framebuffers aren't always
     correctly configured, but still are transferring data [from
     somewhere to somewhere sometimes].
  
 I'm getting lots of messages like [5][6], among others, in
 various cases.

 Of some 3 OpenCL applications I tested, one appeared to complete
 successfully [7]. Running it also produces messages as in [6].
 But the numbers make sense, comparing to e.g. tests of R9 Nano
 (~/mixbench/results/OpenCL/alt_R9-Nano_d1912.5.log) and expectations
 of the GPU chip. This is exciting! Dunno if the benchmark check
 whether the computations are correct, though.

 `clinfo` result [8] is a bit mixed... e.g., "Max clock frequency:
 555Mhz" is wrong.

 Some more tests [9].
