libdrm is always used; that's the API for managing the ring. DRI=false
means to not use the kernel module and do all of the ring management
from user mode. This is a change from how things used to work.

the drm tree has stale kernel bits; you would want to use either the
drm-intel-next or drm-next kernel trees to get current kernel bits. But,
the driver should work correctly with your existing kernel module.

Yeah, just don't copy them at all -- the kernel bits in the drm tree are
not up to date.
