I've just had a chance to upgrade X.org/Mesa ports on my fresh -CURRENT laptop, and noticed that X.org server indeed won't startup unless I load radeonkms.ko module by hand. I understand that this entry specifically talks about it, but would like to clarify a few things if you don't mind: > + The order in which drivers are now attempted is: > + 1) vendor/model specific driver according to PCI IDs > + 2) generic modesetting driver which requires a drm driver with KMS > + 3) scfb, the generic framebuffer driver > + 4) vesa (only if arch is x86) Can you recall what was the previous order? > + This should minimize the need for xorg.conf files.

I don't mind loading it by hand or via kld_list, but still want to know what had broken automatic loading in my case (as it worked fine before). > + driver is already loaded and will fail if there is none.

The > + ATI driver continues to offer better performance than modesetting. Can you elaborate a bit on the last sentense (my context is solely AMD/ATI, I don't own or care about Intel hardware).
