If you have a radeon 9700 or 9800 and it says that these cards aren't 
stable set the env var R300_FORCE_R300 to something, though obviously 
you might experience lockups.

No, not really. aiglx can fail for some reason but dri can still be
working (I have that situation currently due to some path mismatch). As
long as the log says "direct rendering enabled" you still get DRI.

The AST driver doesn't compile since some time now, I'm not sure if
anyone bothers. If you pulled from cvs only, other drivers won't build 
neither (intel, nv) because they are maintained in git. You can safely 
ignore those errors, just use a build script which continues. (If you 
use build.sh, -n should do, though you should check the errors in the 
log afterwards).
