Hi,
uevent support was added to the nouveau DDX in a recent commit. A test is made 
in configure.ac for libudev being present but there is no minimum version. I 
have had problems with this as I am using Fedora 11 which has udev-141 in it. 
This version does not support all of the functions required by the DDX and 
will crash Xorg. At least this function is missing: 
udev_monitor_filter_add_match_subsystem_devtype
I don't know when this was added to udev, but it was definitely after 141.
In
the mean time, I will endeavor to fudge the configuration so that it doesn't
think that udev is installed. Hopefully this will result in a DDX that
doesn't
crash. 
I'm also going to try setting up a partition with Fedora 13 to see what 
happens with that.
Best Wishes,
Bob Gleitsmann
