I figured as much, but I worded my question here as I did on purpose, trying to
elicit self-determination information. In the instant case I was really asking
on behalf of (trying to help) someone who is using an X1400 GPU getting only
black 800x600 output on his external display, but I've run into this error
message multiply before without ever finding out why glamor doesn't find the 128
instructions it requires.

Does this apply to all ATI GPUs too old for the xf86-video-amdgpu driver? How
can a user make such a determination? Does one need to ask a developer for each
GPU one comes across that fails with the default/integrated driver? Can one use
PCI IDs or something else in a lookup table somewhere?
