I do. I disabled it when Maverick came out, because they changed the graphics driver for my card (Radeon, x1200, rs690m) from the.. (I think "r300g?") driver to the Radeon driver, and that caused corruptions (which have never been fixed) that get WAY worse with KMS enabled. I can send you a couple screenshots if you'd like. With KMS, my system is unusable. There are others with this problem, but the bug's never been resolved.
This is a problem specific to the Radeon driver, possibly specific to the x1200/rs690m, and is aggravated by KMS. Well, the bug may have been resolved -- freedesktop.org closed the bug about a week ago as fixed, and said if anyone has graphics corruption issues to try the latest git. ..which I don't know how to do, exactly, so I can't verify one way or the other.
