When starting savage I'm getting this error:
libGL warning: 3D driver claims to not support visual 0x4b
Mesa 6.5.2 implementation error: User called no-op dispatch function (an unsupported extension function?)
Please report at bugzilla.freedesktop.org
xorg-server 7.3, ATI Radeon Mobility 7500, should I provide anymore information?
You could try a newer mesa dri driver. Usually though such errors are the result of an application trying to use a opengl function which is not supported by the driver. You can try setting a breakpoint with gdb at _mesa_error and see what the app was trying to do.
