[Nouveau] Can't use nouveau driver; /usr/lib/xorg/modules/drivers/nouveau_drv.so doesn't exist

[Delan Azabani]

Hi all,

I've compiled nouveau but am having trouble using it as the X driver.
After installation, Xorg.0.log throws

[  3877.874] (II) LoadModule: "nouveau"
[  3877.874] (WW) Warning, couldn't open module nouveau
[  3877.874] (II) UnloadModule: "nouveau"
[  3877.874] (EE) Failed to load module "nouveau" (module does not exist, 0)

Oddly, there is no nouveau_drv.so in /usr/lib/xorg/modules/drivers/ and
I don't know where to find it.
