Savage DRI broken in modular X

[Joachim Frieben]

There seems to be a problem with "mesa-libGL-6.4-4": Before
reinstalling my system today from "rawhide", I had used my
homebrewn, monolithic Xorg 6.9RC1 RPMs. Here, 3D acceleration
was excellent even for the latest rawhide tree before the
move to modular X. "(II) SAVAGE(0): Direct rendering enabled"
looks ok. However, it seems, that the Mesa tree has not been
adapted accordingly. Enabling verbose output, one obtains
for a rebuilt "ppracer" package the following output:

[test]$ env LIBGL_DEBUG=verbose /usr/bin/ppracer

libGL: XF86DRIGetClientDriverName: 2.0.2 savage (screen 0)
libGL: OpenDriver: trying /usr/X11R6/lib/modules/dri/savage_dri.so
libGL error: dlopen /usr/X11R6/lib/modules/dri/savage_dri.so failed
(/usr/X11R6/lib/modules/dri/savage_dri.so: cannot open shared object file:
No such file or directory)
libGL error: unable to find driver: savage_dri.so

Why does it still look for "/usr/X11R6/lib/modules/dri/savage_dri.so"?
I have posted a bug report, see

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=173679

Does anybody have some information on this issue?
