You might want to prepare for the possibility that your card just |
| 28 |
doesn't work with KMS, even different cards from the same brand. |

At home, I have a Radeon FireGL V3400 that just refuses to work with any |
| 31 |
kind of KMS, and I finally gave up. You can disable it either by |
| 32 |
building a kernel that defaults to not having it on, or by passing a |
| 33 |
kernel parameter from Grub ("nomodeset"). |

At work, I have a Radeon HD4350 which works great with KMS on console |
| 36 |
VTY's and in X11, and hardware 3D works fine also. Both machines are |
| 37 |
running Gentoo with the 1.9 Radeon drivers and the 2.6.38.2 kernel. |

KMS is just going to have to be something that works when it works for |
| 40 |
now. |
