You need to add a Modeline for this resolution. Use gtf or cvt to 
generate it.

This is the output of 'gtf 1440 900 -x', I don't have cvt on this box.

   # 1440x900 @ 0.00 Hz (GTF) hsync: nan kHz; pclk: nan MHz
   Modeline "1440x900_0.00"  nan  1440 -2147483648 -2147483648 
-2147483648  900 901 904 901  -HSync +Vsync

VIA driver are really different from either the xorg or openchrome 
driver. Forget about xine or mplayer with them, you'll need their forked 
version of xine-lib and mplayer. If you choose this route (which I'll 
strongly advice against for various reasons), please note this is not 
supported here.

Mplayer doesn't support openchrome's XvMC implementation out of the 
box,it needs a patch. take a look at the wiki and the mailing list 
archives. An updated patch has been posted not that long ago.

Probably, I'm not sure what Mandriva has done to the driver. I'll need 
to take a look at their patches.

No MPEG4 acceleration with openchrome driver. This is not implemented yet.
