    that changed the GART VM start offset.  It fixed some machines, but
    seems to continually interact badly with some X versions.
    
    Quoth Ben Herrenschmidt:
    
      "So I think at this point, the best is that we keep the old bogus code
       that at least is consistent with the bug in the server. I'm working on a
       big patch to X that reworks the memory map stuff completely and fixes
       those issues on the server side, I'll do a DRM patch matching this X fix
       as well so that the memory map is only ever set in one place and with
       what I hope is a correct algorithm..."
