I get this message when trying to start savage 2 in ubuntu Jaunty alpha with latest updates. 
I have Intel Video Card: 00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 03)

On xorg.conf I added this line to work fine with opengl:

Section "Device"
	Identifier	"Configured Video Device"
	Option          "AccelMethod"           "UXA"
EndSection

In attachment you will see dmesg and glxinfo...

I have no idea if it could be fixed, but I made this report trying to help in something.
