I've Found the solution..

I've read the source code from savage_driver.c and the problem was
coming from SavagePanningCheck(...), because CrtcVDisplay was eqal to
384, and the function was returning true, and Xvideo was disabled.

After more research, I found that CrtcVDisplay was bad because I was
using an Interlaced ModeLine. I've changed my HorizSync in order to have
a non-interlaced Modeline.

I can yet use Xv!!!!!!

Perhaps, it would be better, if the driver was sending a Warning message
that says: "Error in SavagePannigCheck.... Xv can't be used"
