Ok, I found a pervasive mistake in the new glamor code -- my _nf
functions were not falling back to fb/mi when the driver would be unable
to access the pixmaps -- they weren't calling
glamor_ddx_fallback_check_pixmap ever.

I've fixed that, which makes Eric's patched xf86-video-intel 'just work'
with the new acceleration code.

I'd love to know if this also fixes radeonsi, but I don't have any
hardware to try it on.

Can you isolate which tests are causing problems? I'm not seeing this; I
assume that's because of the difference in GL drivers.
