I think this refers to KMS_DRIVER_MINOR in the kernel drivers/gpu/drm/radeon/radeon_drv.c.

So it looks like it will not be supported before 3.10.
(In the actual merging to agd5f/drm-next-3.10 KMS_DRIVER_MINOR was increased to 33, so I guess the detection will be slightly wrong)
Thanks, that sounds right.
But it does seem to work with 3.9 when I simply set it to true. xonotic would complain that texture compression is not supported without it, but with it it doesn't complain and renders completely fine. Does it not work in every case?
