Vainfo work fine now:
libva: libva version 0.30.4-sds2
libva: va_getDriverName() returns 0
libva: Trying to open /usr/lib/va/drivers/i965_drv_video.so
libva: va_openDriver() returns 0
vainfo: VA API version: 0.30
vainfo: Driver version: i965 Driver 0.1
vainfo: Supported profile and entrypoints
       VAProfileMPEG2Simple            :	VAEntrypointVLD
       VAProfileMPEG2Main              :	VAEntrypointVLD

mplayer working too. But it has lot of artifakts in fullscrean mode.
