Replying to digest format mail is a real pain :(

As further data point, I am also using the zx6000. I do get a change
in behaviour now having upgraded kernel xorg-server-Xorg and xorg-drv-
bits to the latest builds as of yesterday. Previously glxgears gave
the DRM message and did not fall back to indirect rendering - ie it
didn't work at all. Now it does fall back and run the app correctly
(and also other GL programs which were failing are now working).

Here are the strace bits for the failing DRM in glxgears:

Card0 looks like:
