Sanctuary used to work quite fine with r300g driver, now it freezes with with
black screen (100% CPU and slowly increasing memory consumption) while loading.

    glsl: Reject shader versions not supported by the implementation

    Previously we'd happily compile GLSL 1.30 shaders on any driver.  We'd
    also happily compile GLSL 1.10 and 1.20 shaders in an ES2 context.
    This has been a long standing FINISHME in the compiler.

    NOTE: This is a candidate for the 7.9 and 7.10 branches


I don't know if this is a bug or a feature. R500 cards are not officially
supported with 2.3 version so it may use some 1.30 shaders, however I've also
tried older version which list Radeon X1xxx card as supported and it also
freeze. And even 2.3 version supports GeForce 7xxx which is imho also not able
to run 1.30 shaders. 

It can be also reproduced with llvmpipe.
