Ho aggiunto Load "dri" ad XF86Config (avevo sbagliato a backupare il file), riporto le sezioni più interessanti...

(II) LoadModule: "dri"
(II) Loading /usr/X11R6/lib/modules/extensions/libdri.a
(II) Module dri: vendor="The XFree86 Project"
compiled for 4.2.1, module version = 1.0.0
ABI class: XFree86 Server Extension, version 0.1
(II) Loading sub module "drm"
(II) LoadModule: "drm"
(II) Loading /usr/X11R6/lib/modules/linux/libdrm.a
(II) Module drm: vendor="The XFree86 Project"
compiled for 4.2.1, module version = 1.0.0
ABI class: XFree86 Server Extension, version 0.1
(II) Loading extension XFree86-DRI

Però se da console lancio glxinfo...
name of display: :0.0
libGL error: failed to open DRM: Operation not permitted
libGL error: reverting to (slow) indirect rendering
display: :0 screen: 0
direct rendering: No

Da root ovviamente non c'è glxinfo per verificare... Di chi devo fidarmi? XFree.0.log, glxinfo o vediamo di farli combaciare?

Segnalo qui l'aggiornamento della mia guida, visto che non si era mai posto il problema del mode 0666 (c'è sempre da imparare ), sperando che possa essere utile a qualcuno anche in futuro
