Actually, looking through the patch now... Two things jump out at me...
We can't currently update libdrm in the ports collection without
breaking nouveau.  The second is, don't enable libdrm_radeon, even when
we can.  libdrm_radeon is only needed for TTM/KMS enabled radeon and may
cause upgrade/build issues if it exists.
