I have filed a tag request:
to get xorg-x11-drv-nouveau-0.0.15-2.20090805git712064e.fc12 into the
alpha, because a mailing list thread and two bug reports lead me to
believe it's needed for nouveau to actually work. At the time of the
xorg-x11-server 125 breakage which is known, nouveau reporters reported
X stopping working just like everyone else, but they seem to need the
updated nouveau _as well as_ the update xorg-x11-server packages to make
things work again. Just updating xorg-x11-server does not do the trick.
Anyone with Rawhide and an NVIDIA video card, if you could confirm the
request, that'd be great. Thanks!
