Long story short: Disable ColorTiling in xorg.conf when using bitmap
fonts on a Radeon.
While searching for clues on this problem, I found this:

Thanks all for your help and suggestions. I'll summarise what further
testing I've done:
I believe 3D acceleration is working. `glxgears` runs and seems to
achieve a smooth 60 Hz. The __memcpy_sse2_unaligned load doesn't seem
to increase due to running glxgears.
