Bearing in mind I have never looked at the .ko modules in 2.5, from
reading Alexander's post it looked as if they were typically created
from more than one .o file. Assuming that the tdfx driver in 2.5/2.6
has not been updated recently, you probably need to look a bit deeper
into the kernel's Makefile to see how its .ko gets created. And if it
has been updated, you need to bug the maintainer (if there is one).
Apologies if your posting above is a verbatim copy of what the kernel
As to downloading X from cvs, you probably need to download the whole
tree, and bear in mind that it may or may not compile on any particular
Just on the offchance it might be something simple : your original
posting showed that the kernel believed it had loaded dri, but by the
time you ran glxinfo it wasn't working. Was there anything in the X log
associated with dri ? This isn't the old "only root can use dri unless
the permissions are changed" problem, I hope.
