	I was trying to separate libdrm_nouveau(2.4.12) and libdrm(2.4.17).
	In thus environment, xf86-video-nouveau can compile with few
	patches.  But xf86-video-nouveau freeze and reset on start X:(.

	I saw diff nouveau codes from 2.4.12 and 2.4.17, I can't back
	port from 2.4.12 to 2.4.17:-).  It quite too hard for me.
	Maybe, I think reimplementation of codes related DMA.

	So I'll try to work coexistence with Mesa3D(7.4.4)/libdrm(2.4.12)
	and Mesa3D(7.6.1)/libdrm(2.4.17).
