It might.  The tdfx driver isn't threadsafe at this point even though
the Mesa core is.

I've *got* to write a FAQ on this.  Installing a new version of Mesa
inside of XFree86 4.0 is not for the faint of heart!  If you're lucky,
you can replace all the files in xc/extras/Mesa from newer versions
from Mesa CVS, recompile the X server's GLX module, recompile all DRI 3D
driver modules, recompile the libGL.so library (just to be safe) and it'll
work.  But since Mesa 3.3 is still under development I occasionally
introduce new source files and that requires modifying the XFree86
Imakefiles.  It's really easy to make a mistake there and get a variety
of problems as a result.

I don't recommend touching the Mesa sources inside XFree86 unless
you really know what you're doing.  I've been too busy to help people
that try this and get stuck.  Sorry.
