Bug: nouveau 64 bits "Xorg -configure" fails miserably Scientific Linux 6.0

[jdow]

Just passing this bit of wisdom learned the hard way back to the
Fedora community...

"Xorg -configure" fails miserably. It produces a configuration
that will not load.

There are two errors in the configuration created.

First it generates "nv" rather than "nouveau". If nouveau is the
default driver loaded it should appear as the driver name.

Second it gives a bad ModulePath line "/usr/lib/xorg/modules" instead
of "/usr/lib64/xorg/modules".

Once those two errors were fixed I was able to put in modelines and
run my Gateway FHD2401 LCD monitor full screen.
