[LUG] 3D/GL support win x4.2.0, 2.4.4 and a voodoo 3

[Paul Weaver <P.J.Weaver@xxxxxxxxxxxx>]

I've gone through all the DRI FAQ's, and installed the tdfx and tdfx_drm 
drivers (well, debian did). However gl apps (and kde apps) give

libGL error: failed to open DRM: Operation not permitted
libGL error: reverting to (slow) indirect rendering

(this is as user, and as root, and I've set the permissions correctly in 
XF86Config-4 (Mode 0666))

Anyone got any experience with XFree 4 and 3dfx?

glxinfo gives
direct rendering: No
OpenGL vendor string: VA Linux Systems, Inc.
OpenGL renderer string: Mesa GLX Indirect
OpenGL version string: 1.2 Mesa 3.4.2

dmesg gives
[drm] AGP 0.99 on Intel 440BX @ 0xd0000000 128MB
[drm] Initialized tdfx 1.0.0 20000928 on minor 61

and

fb: Voodoo3 memory = 16384K
fb: MTRR's  turned on
tdfxfb: reserving 1024 bytes for the hwcursor at d18e9000
