xv crashes in savage_drv when trying to play (any) DVD with mplayer or xine

The video card is ProSavage KN133 (hp pavilion ze1210 laptop)

when I'm playing other video files (mpeg4) it's fine, and if I turn off xv in
the player for DVD it works but rather slow.

this happens at least on two releases: RC0 and RC4 from Mandriva Cooker

Don't know how easy it's to fix so marking as blocker for now, because there's
no way to watch DVD with this card.

Here's backtrace, Xorg.log for two releases will be attached
