And this continues to be the case for the mm3 and mm4 kernels.

Some testing here indicates that if I replace *all* the glx stuff with 
that from MesaLibs, I get around 550 fps, but with 100% cpu going to 
glxgears.  glxinfo says drm = no

With the 6.8.1 glx stuff installed, glxinfo says drm - yes, and I get 
10 fps at 0% cpu, even at full screen, something the MesaLibs stuff 
can't handle at all.  Other screen actions do seem to be quite snappy 
even if glxgears is a crippled dog.

Noting John Smirls announce on lkml just now, I wonder if I should be 
a tester of his new drm?
