Bug#724576: libgl1-mesa-glx:libGL error:failed to load driver:nouveau

[Paul Garlick <it@tourbillion-technology.com>]

Dear Maintainer,

This problem persists with libgl1-mesa version 10.1.4-1 on iMac G4 
powerpc (NV34 graphics card).

Testing with an Asymptote example:

$ asy -V cube.asy

the command produces the 'failed to load driver' message but no 
graphical output.  Downgrading the libgl1-mesa-dri package (to 9.1.7-1) 
works around the problem, as mentioned in message #30.  However, even 
with the downgraded package there is still a problem with large 
graphical output.  FreeCAD, for example, causes the GPU to lockup in 
full-screen mode.  This could be the same problem reported in 
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=744387 .

Cheers,

Paul.
