Description erich f 2008-04-04 18:25:11 UTC
Tested with modules from the Kernel and xorg-server that pertain to
an r128 chip. Found that:

             1) Xserver doesn't come up at all with the kernel modules.
             2) Xserver comes up with xorg-server modules, but without
             3) With a combination of both kernel and xorg-server modules
                the Xserver comes up; but, once again, no DRI.

It is case 3 that I've tested the most, and have the details

Reproducible: Always

Steps to Reproduce:
1.Build xorg-server with VIDEO_CARDS="r128"
2.Build the kernel with the pertinent modules
3.Run xorgconfig to get custom xorg.conf file. 
4.Type startx

Actual Results:  
Xserver came up (with twm). Typed glxinfo, and found DRI was not present

Expected Results:  
Expect DRI to be present.

possibly your configuration is bad
> (WW) R128(0): [agp] AGP failed to initialize -- falling back to PCI mode.
incomplete agp support in the kernel

> /usr/lib/dri/ cannot open shared object file: No such file or directory
mesa compiled with wrong USE/VIDEO_CARDS flags

See 82039,

       Something was fixed back in 2005 before Xorg was modularized. This bug
is now back when once it was fixed.

       Someting else has come up, and a Google search has shed no light for
me. The first occurence of an error in Xorg.0.log is

       (EE) R128(0): No DFP detected

       DFP means Digital Flat Panel. This suggests that, in an effort to
embrace new technology, Xorg is causing legacy code to break.

Can you still reproduce with xorg-server 1.5 and a newer kernel?
