No negative sides to it, really. Speed will also benefit (not directly |
| 11 |
from KMS but rather from TTM/GEM) since the biggest problem with the |
| 12 |
open source drivers right now is the lack of a memory manager (this is |
| 13 |
the main reason why the closed source drivers perform better by an order |
| 14 |
of magnitude, even though they have the memory manager in user space). |

I'm not sure about the mode for external displays. The configuration |
| 17 |
will probably still happen at the same place, though under the hood the |
| 18 |
work will be done by the kernel. |
